later.

netchild's mega-patch to isolate compiler dependencies into a central

place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

In the spirit of amd64/include/stdarg.h rev 1.6; add __va_copy

2004-07-06T07:47:09+00:00

(but keep it conditional on __ISO_C_VISIBLE >= 1999.

Why?  Our out /usr/src/contrib assumes it, and more than a few ports have
an autoconf that looks for __va_copy because it is available on glibc.
It is critical that we use it on PowerPC.  It generally isn't a problem
for i386 and its ilk because those platforms can get away with cheating
the C standard, using a plain assignment.

o Add conditionals to allow va_list to be defined in other headers.

o Standardize on _MACHINE_STDARG_H_ to allow multiple header includes.
o Restrict the definition of va_copy() to C99 environments.

Implement C99's va_copy() macro.

o  will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_
    #endif
  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED
