*Duh*

I _want_ to see warnings about (wrong) casts, but I do not want gcc to warn
when it should not...
I compile all my sources with:

-Wall -W -Wpointer-arith -Wshadow -pipe -Wbad-function-cast -Wcast-qual
-Wmissing-prototypes -Wstrict-prototypes -Wmissing-declarations
-Wwrite-strings -Werror -pedantic-errors -ansi -trigraphs -fsigned-char

and it's always worked for me. I'm not about to adapt my warning levels
just because of some bug in gcc-2.95.2...
I admit that it's a disgusting "feature" and that there are other ways
to work around it, but this simply breaks the ANSI compatibility of gcc.
