No, I'm going to commit something a little different instead. You also
got half the gcc4 warnings in gdbserver, and not the other half - maybe
because PowerPC and i386 have different signedness on char?
I agree with Mark that we ought to check for socklen_t before using it.
There were some systems where the type was actually size_t, but I don't
care anywhere near enough to work out a test for that.
Also sig really should be an unsigned char, not a signed char. That
ripples down a bit.
Please let me know if you find any further warnings.
