Children these days... This variety existed since the 80s.
PDP-11 was signed, IBM 370 - unsigned.

Yep, found that out the hard way. It annoyed me enough that I went

I did, because due to XFS's history, it maked an assumption that's not true on
x86.
We had -funsigned-char in the Ma

Yep, found that out the hard way. It annoyed me enough that I went
digging in the gcc source to find the answer for all platforms
According the standard, char is supposed to be a distinct type from
signed/unsigned char.
btw, most commonly-used compilers (gcc, msvc, etc.) does use these
defaults, but you can't even assume that for every compilers.
If one wants to check the signedness of char, she could check CHAR_MIN
is equal
Did you know that "char" defaults to "signed char" on x86 but "unsigned char"
on ppc and arm? I didn't.
Just a heads up.
