Subject: C99 sections for headers and freestanding [PATCH]
Message-Id: <E18mZmU-0000fg-00@phekda.freeserve.co.uk>
Reply-To: djgpp-workers AT delorie DOT com

Hello.

Below is a patch to add C99 sections to headers that have
sections for free-standing implementations. (I committed almost
all of the patches for headers without definitions in
the free-standing sections.)

The major change is for <stdarg.h>. The C99 standard says that
the definitions in <stdarg.h> should be available in a free-standing
implementaion. Currently they are not. This patch fixes that.

OK to commit?

Thanks, bye, Rich =]
