49c19fe3e5 Sync up error.c with glibc 
This is a partial sync-up of error.c with glibc.  The following
changes went in:

- Get rid of the INTUSE macro
- Remove unused macro ALLOCA_LIMIT
- Fix a potential buffer overflow in error_tail (sourceware bz #15672)
- Fix a potential NULL dereference in strcmp

Rationale:
Microsoft renamed the "Win32 API" to "Windows API", as it is available
on both 32-bit and 64-bit Windows systems.
But in gnulib, we treat Cygwin like a Unix platform, therefore the main
line of distinction is between "native Windows" on one side and Unix/
POSIX systems on the other side. More details in
<https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00027.html>.

cd6df927ef (SIZE_MAX) [!defined SIZE_MAX]: Define. 
(error_tail): Do not loop, reallocating temporary buffer, since
the original size is big enough.  This avoids one potential size
overflow calculation.  Check for size overflow when calculating
temporary buffer size.  Free temporary buffer when done, if
it was allocated with malloc; this closes a memory leak.
