dup2, fcntl, fcntl-h: port to AIX 7.1
This fixes some porting problems discovered when testing the latest
grep snapshot on AIX 7.1. I don't think if fixes any bugs
in grep but it could be important for other applications.
* doc/posix-functions/dup2.texi:
* doc/posix-functions/fcntl.texi:
* doc/posix-headers/fcntl.texi:
Document AIX bugs.
* lib/fcntl.in.h (O_CLOEXEC, O_NOFOLLOW, O_TTY_INIT) [_AIX]:
Define to 0 if outside 'int' range.
* m4/dup2.m4 (gl_FUNC_DUP2):
* m4/fcntl.m4 (gl_FUNC_FCNTL):
Check for getdtablesize. If it's available, test a value just
outside its range instead of testing 1000000. When cross-compiling,
guess that AIX will fail this improved test.
