Seen in, e.g. ports/sysdeps/alpha/soft-fp/ots_mul.c.
The problem here is we have a switch on the class of X*Y, followed by
a switch on the class of R. The exponent field of R really is not set
by the first switch for NaN outputs, because we know it's not going to
be used. The compiler is not smart enough to see through this.
By pulling the exponent computation out of the NORMAL*NORMAL path, we
will not be pessimizing the most common case, while still providing an
arbitrary value to satisfy the compiler.
Some arches do not have a __NR_fadvise64 but do have __NR_fadvise64_64.
If the former is unavailable, fallback to the latter.

The __builtin_bswap* functions were introduced in gcc-4.3, not gcc-4.2.
Fix the __GNUC_PREREQ tests to reflect this.
Otherwise trying to compile code with gcc-4.2 falls down:
In file included from /usr/include/endian.h:60,
from /usr/include/ctype.h:40,
/usr/include/bits/byteswap.h: In function 'unsigned int __bswap_32(unsigned int)':
/usr/include/bits/byteswap.h:46: error: '__builtin_bswap32' was not declared in this scope
/usr/include/bits/byteswap.h: In function 'long long unsigned int __bswap_64(long long unsigned int)':
/usr/include/bits/byteswap.h:110: error: '__builtin_bswap64' was not declared in this scope

In BZ #12724, partial support for POSIX 2008 fclose behavior was added.
Since it isn't entirely conforming to the spec, some applications are
known to be breaking in this intermediate state. So revert the partial
support until we can get things fully implemented.
This reverts commit fcabc0f8b1.

In commit 26889eacc2 (Remove
__ASSUME_POSIX_CPU_TIMERS), all users of HAS_CPUCLOCK were
dropped. Punt the fallback definition too.
