by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.
This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.
I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.
Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.
* Add prototype for vfscanf to <stdio.h>.
* Remove #define of vfscanf to __svfscanf from <stdio.h>.
* Include local.h in libc files which need __svfscanf.
* Add vfscanf weak alias to __svfscanf.
Fixes standards/16997.
NOTE: libc minor not bumped -- ride on the bump to 12.84 made by
itojun today.
software can become greatly confused.
This fixes 4 GCC 3.2 testsuite failures.
This is a stop-gap measure which can be easily applied to the 1.6
release branch. A different fix for the trunk is forthcoming.
as __null with egcs 1.0 (GCC 2.90) and above. As several headers are affected
by this change, move the definition into a new header file, <null.h>, to ease
maintenance.
wrapper, and make sure we won't use these decl's as such with C++ linkage(!).
Also, make _XOPEN_SOURCE protection of popen()/pclose() decl's a bit more
restrictive.
_POSIX_SOURCE or _XOPEN_SOURCE at compile time, use __RENAME() to call
__posix_rename() instead of rename() in order to remove the requirement of
linking against libposix.
getc_unlocked(), getchar_unlocked(), putc_unlocked(), & putchar_unlocked().
Added macro definitions for the latter four functions.
Changed so that getc(), putc(), clearerr(), feof() and ferror() macros
are not defined if _REENTRANT is defined so that thread-safe function
versions will be used instead.
