[Bug c/25892] New: -Wpointer-sign creates problems for Emacs

[jbuck at gcc dot gnu dot org]

The original report from RMS stated:

"GCC 4 when compiling Emacs gives annoying warnings about
mismatched signs of pointer target types.  To turn this
off is not trivial, since the -Wno-pointer-sign option
itself causes a diagnostic from older GCC versions.
It makes compilation fail."

Evidently changing Emacs is not an acceptable option.
After discussion with the SC and the original contributor
of the -Wpointer-sign patch, the SC agreed that
the best solution would be for -Wpointer-sign not to be
enabled by default, but only if -Wall or --pedantic is present.

Since the SC promised this fix to RMS, it needs to be considered
a release blocker for 4.1.

(I don't know about 4.0.3, probably best to do it there too).
