Yes, Bryan is working on a fix.  The issue has to do with how to properly
detect which compiler is used.  If Bryan isn't able to fix it soon I'll
either revert or add a clunky workaround.  (If you check for GCC first
rather than clang first which is what Makefile.inc1 does, then you
happen to avoid the bug with X_COMPILER_TYPE being set)
