Thanks for this assistance, Matthias. Much appreciated. :-) Yes, I
really don't like GCC. I think it still misses some things even in
pedantic mode.

The most notable problem is the fact that char, unsigned char and
signed char are three *incompatible* types. There exist implicit
conversions between those, but they are not compatible. Concerning
pointer compatibility, it is defined that only pointers to compatible
types are compatible. So, you cannot assign a char* to an unsigned
char* to a signed char* (in no combination). GCC allows this and this
is sloppy.

I can back up this claim with references to the C standard if somebody
thinks I'm wrong. ;-)
