Details:

When compiling -base with clang, I get:

gdomap.c:2499:12: error: invalid instruction mnemonic 'setcb'
              if (FD_ISSET(i, &rfds))

Using GNUstep trunk r31638 on GNU/Linux 2.6.35, LLVM/clang from trunk
r119905, and glibc 2.12.1 from distro repository.

It does not matter if I use libobjc2 from GNUstep or libobjc from GCC 4.5.1.
The attached build logs are with the latter, only installing -make and -base
using:

-make: ./configure --with-layout=gnustep --prefix=/
-base: ./configure --with-ffi-include=`pkg-config --variable=includedir
libffi`

Interestingly, GSRunLoopCtxt.m also uses FD_ISSET, but compiles fine. Both
libgnustep-base.so.1.21.1 and all the objc tools are built by the time gdomap
compile fails.
