Compiling the following fragment with gcc -Wall gives me a warning
about an unused variable, gcc -Wall -Werror turns that into an error.

int main(int argc, char **argv) {
int i;
return 0;
}

The issue here is if I run this on e.g. XP UK I get messages containing
"warning:" and "error:". Doing the same under XP JPN gives me "error:" and
something unreadable for the warning case (looks like an attempt to read
from a bogus pointer).

I guess that NLS under windows doesn't work as on linux...
