System: Linux decomino 2.2.18 #1 Sun Jan 7 21:04:55 UTC 2001 i686 unknown
Architecture: i686

	
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-cvs/configure --prefix=/opt/gcc/snapshot --disable-shared --enable-threads=posix --with-system-zlib
>Description:

This is a PR to track an issue previously reported on gcc-bugs
<URL: http://gcc.gnu.org/ml/gcc-bugs/2000-11/msg00545.html >.  When
-funsigned-char -fsigned-char is used on a system with signed chars,
chars are signed but __CHAR_UNSIGNED__ is defined.

>How-To-Repeat:

See message cited.

>Fix:

Either leave until specs / option parsing get redesigned, or kludge
something so that the existing code that knows (when handling specs)
that -f<foo> and -fno-<foo> are opposites also knows that
-fsigned-char and -funsigned-char are opposites (and similarly,
-ffreestanding and -fhosted, with similar problems associated with
__STDC_HOSTED__).

     This is a regression from 2.95.2.  I've asked Bruce Korb for help with this one.  I'm assigning it to myself so that I can find it easily later.
