832e8b7f9a Eliminate 61 warnings emitted at WARNS=2 (leaving 53 to go). 
Only warnings that could be fixed without changing the generated object
code and without restructuring the source code have been handled.

680c2aca55 Initial implementation of the C99 feature whereby calling freopen() with 
a NULL filename argument allows a stream's mode to be changed. At the
moment it just recycles the old file descriptor instead of storing the
filename somewhere and using that to reopen the file, as the standard
seems to require. Strictly conforming C99 applications probably can't
tell the difference but POSIX ones can.

58ac802ff1 Restore Peter's version of static __sF. There's too much pain for it 
to be static for 5.0.  I may remove this for 5.1 or 5.2.  No more
binaries or libarires will be generated with __sF starting as of
yesterday.  Originally the plan had been to eliminate this for 5.0,
but we didn't get the __std{in,out,err}p changes merged into -stable
until yesterday (rather than in September 2001 like it should have
been).  Given that didn't happen on time, we can't do the other part
of the scheme now.

# Please do not change this without talking to me first.
