Hello.

They are standard now.

They are standard now.

I haven't been through the headers yet, to check whether things are declared
in the right places.

I think we should have another ANSI section in the header files. Something
like this, perhaps:

#ifndef __dj_ENFORCE_ANSI_FREESTANDING

...C89 declarations here...

#if (__STDC_VERSION__ >= 199901L) || !defined(__STRICT_ANSI)
...C99 declarations here
#endif

#ifndef __STRICT_ANSI__

...

#ifndef _POSIX_SOURCE

...

#endif
#endif
#endif

There would also be another section in <libc/stubs.h> for ANSI C89 functions
that call ANSI C99 functions (if there are any). tests/libclink would need
updating too.

Bye, Rich =]
