I think that's the issue. But since that code fragment isn't in the bash
or readline configure.ac, it's inserted by autoconf, probably as part of
AC_PROG_CC.

The documentation for AC_PROG_CC doesn't mention setting GCC to the empty
string if the compilation is not using gcc, but it seems to do that.

I guess I'll have to work around it.
