Joel Brobecker 1f99f6d068 strerror.c: Do not declare sys_nerr or sys_errlist if already macros
This fixes a MinGW warning in libiberty/strerror.c.

2015-01-19  Eli Zaretskii  <eliz@gnu.org>

        * strerror.c <sys_nerr, sys_errlist>: Declare only if they aren't
        macros.

Joel Brobecker 5af04e20f6 Use strtod instead of strtold in libiberty/d-demangle.c
strtold is currently used to decode templates which have a floating-point
value encoded inside; but this routine is not available on some systems,
such as Solaris 2.9 for instance.

This patch fixes the issue by replace the use of strtold by strtod.
It reduces a bit the precision, but it should still remain acceptable
in most cases.

libiberty/ChangeLog:

        * d-demangle.c: Replace strtold with strtod in global comment.
        (strtold): Remove declaration.
        (strtod): New declaration.
        (dlang_parse_real): Declare value as double instead of long
        double.  Replace call to strtold by call to strtod.
        Update format in call to snprintf.

Andrew Burgess 173373c6f6 Delete temporary string within demangler even in failure cases.
A call to demangle_template might allocate storage within a temporary
string even if the call to demangle_template eventually returns
failure.

This will never cause the demangler to crash, but does leak memory, as
a result I've not added any tests for this.

Calling string_delete is safe, even if nothing is allocated into the
string, the string is initialised with string_init, so we know the
internal pointers are NULL.

libiberty/ChangeLog

	demangle_template fails.

Pedro Alves 6143b8235e Fix demangler testsuite crashes with CP_DEMANGLE_DEBUG defined
Running the demangler's testsuite with CP_DEMANGLE_DEBUG defined
crashes, with:

 Program received signal SIGSEGV, Segmentation fault.
 0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567
 567       switch (dc->type)

 (gdb) bt 3
 #0  0x000000000040a8c3 in d_dump (dc=0x1, indent=12) at ../../src/libiberty/cp-demangle.c:567

Note dc=0x1, which is obviously a bogus pointer.  This is the end of
d_dump recursing for a component type that that doesn't actually have
subtrees:

 787       d_dump (d_left (dc), indent + 2);
 788       d_dump (d_right (dc), indent + 2);

This fixes the two cases the testsuite currently trips on.

Mike Frysinger 369be6981b libiberty: fix --enable-install-libiberty flag [PR 56780]
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted.  So we end up initializing properly
at the top only to reset it at the end all the time.
