glibc HEAD from git currently cannot build with clang:


../include/sys/stat.h:16:15: error: cannot apply asm label to function after
its first use
hidden_proto (__fxstat)
~~~~~~~~~~~~~~^~~~~~~~~
./../include/libc-symbols.h:420:19: note: expanded from macro 'hidden_proto'
  __hidden_proto (name, , __GI_##name, ##attrs)
  ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./../include/libc-symbols.h:424:33: note: expanded from macro '__hidden_proto'
  extern thread __typeof (name) name __asm__ (__hidden_asmname (#internal)) \


For the relevant discussion from clang side please see:

Are these macros something that could be patched on the glibc side?  Thank you.
