This is correct. I changed two items.
1) switched from gcc to xlc
2) changed -qchars=unsigned (was -qchars=signed)
Most of the regression tests failed with -qchars=signed and all passed without
so much as a whimper when -qchars=unsigned. Don't know why this happened, or if
it makes any difference on your platform, but that's what AIX needs to work.
