There is at least one place (I didn't look for others) where the
source code for perl expects the type "char" to be a signed quantity.
(Actually, it just expects the result of an addition of a char and 
an int to be signed.  Check out doarg.c line 189 patchlevel 3.044)
Some compilers (RISC C Compiler v2.11) treat it as unsigned.

I was seeing some pretty bizarre regular expression replacement
behavior.  I got around it by giving "-signed" to the MIPS cc
command.
