too. Don't write to file and especially don't close handle if file
couldn't be created. Set delete disposition if writing failed,
instead of calling unlink_nt.
* include/io.h (__finddata64_t, __wfinddata64_t): changed member 'size'
from '_fsize_t' to '__int64' to be consistent with the other ...64
structures and the value set there is 8 bytes not 4. Add guard for both
as the are only used by functions available from 6.1 on.
* include/malloc.h (_HEAP_MAXREQ): Define.
(_aligned_offset_recalloc): Define.
(_aligned_recalloc()): Define.
* include/math.h: fixed a typo in a comment.
(atanhf): Fixed declaration.
* include/wchar.h (__wfinddata64_t): changed member 'size' from '_fsize_t'
to '__int64' to be consistent with the other ...64 structures and the value
set there is 8 bytes not 4. Added guard as this function is only used by
functions available from 6.1 on.
* include/sys/stat.h: some members of 'stat' were declared with types with
a prefixed underscore, while the ones without the underscore should have
been used. Added guard to '__stat64' as it is only used by functions
available from 6.1 on. Added the wide character versions of the
exec()/spawn() family for completion
(_stati64): changed the type of the 'st_mode' member from 'unsigned int' to
'_mode_t'
* include/sys/timeb.h (timeb, _timb): changed the type of the 'time' member
from 'long' to 'time_t'
(__timeb64): moved declaration of structure directly before the declaration
of the function '_ftime64()', so it is guarded as well
* include/sys/utime.h (__utimbuf64): moved declaration of structure directly
before the declaration of the functions using it, so it is guarded as well

* mingwex/gdtoa/mingw_snprintf.c (x_sprintf): Correct LEN_L typo in 'l'
case. Add missing break in 's'/LEN_S case.
(mmap64): ...define as local pointer to make mmap thread-safe.
Accommodate throughout. Only initialize fh_disk_file after file could
be opened with GENERIC_EXECUTE access. Call fstat_by_handle instead of
fstat to avoid overhead.
