e0554a531f 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.

21d4d23958 Lock stdin on entry, unlock on return, use __sgetc() instead of getchar()
to avoid locking the stream for each character and to avoid input being
scattered among multiple threads.

c297498757 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.

c906b66373 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.

bd25c6f476 The field width for single-byte string conversions (%c, %s, %[) is the
maximum number of bytes that may be stored in the array, not the maximum
number of wide characters to read. The wording of the standard unfortunately
does not make this clear.
