The *_HAS_* floating-point feature macros are defined as 0/1 rather than
#undef/#define settings by gcc/c-family/c-cppbuiltin.c. Consequently we
choose to use infinity and NaN features even with non-IEEE-754 targets
such as `vax-netbsdelf' that lack them, causing build warnings and
failures like:

When producing error and warning messages, libgfortran writes a
message by using many system calls. By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.
In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write. In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.

Fortran 2018 adds a new QUIET specifier for the STOP and ERROR STOP
statements, in order to suppress the printing of signaling FP
exceptions and the stop code. This patch adds the necessary library
changes, but for now the new specifier is not parsed and the frontend
unconditionally adds a false value for the new argument.

Following the change to use size_t for Fortran character lengths (PR
78534), this patch modifies the Coarray ABI in a similar way. The
single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.
This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.
I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.
Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.
I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.
This is v5 of the patch. v4 was applied but caused breakage on big
endian targets. These have been fixed and tested, thanks to access to
the GCC compile farm.
Overview of v4 of the patch: v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.
Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.
Regtested on x86_64-pc-linux-gnu, i686-pc-linux-gnu and
powerpc64-unknown-linux-gnu. Also regtested all three targets by
modifying gfortran-dg.exp to also test with "-g -flto", no new
failures observed.

The current F2018 draft (N2137) specifies behavior of the RECL=
specifier in the INQUIRE statement, where it previously was left as
undefined. Namely:
- If the unit is not connected, RECL= should be given the value -1.
- If the unit is connected with stream access, RECL= should be given
the value -2.
Further, as PR 53796 describes, the handling of RECL= is poor in other
ways as well. When the recl is set to the maximum possible
(GFC_INTEGER_8_HUGE / LLONG_MAX), which it does by default except for
preconnected units, and when INQUIRE(RECL=) is used with a 4 byte
integer, the value is truncated and the 4 byte value is thus
-1. Fixing this to generate an error is a lot of work, as currently
the truncation is done by the frontend, the library sees only an 8
byte value with no indication that the frontend is going to copy it to
a 4 byte one. Instead, this patch does a bit twiddling trick such that
the truncated 4 byte value is GFC_INTEGER_4_HUGE while still being
0.99999999 * GFC_INTEGER_8_HUGE which is large enough for all
practical purposes.
Finally, the patch removes GFORTRAN_DEFAULT_RECL which was used only
for preconnected units, and instead uses the same approach as describe
above.
Regtested on x86_64-pc-linux-gnu, Ok for trunk.

Glibc 2.17 made __secure_getenv an officially supported function, and
renamed it secure_getenv. The libgfortran configure has checked for
both of these, per
https://sourceware.org/glibc/wiki/Tips_and_Tricks/secure_getenv.
Unfortunately, while the dynamical library (libc.so) retains the
__secure_getenv symbol for backwards compatibility, the static library
(libc.a) does not. This means that a libgfortran.a compiled against an
older glibc will not work if one tries to link against a newer
libc.a. This creates problems for providing gfortran binary
distributions that work on as many target systems as possible.
Thus, retain the support for __secure_getenv but call it only via a
weak reference.
Regtested on x86_64-pc-linux-gnu.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.
This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.
I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.
Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.
I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.
This is v4 of the patch. v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.
Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.
Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu.
