<pre>I don't know whether this is something that needs to be fixed in Clang,
but at least I want to document this incompatibility with GCC in form of a bug.
% cat b.c
extern void FOO();
void call() { FOO(); }
extern __typeof (FOO) FOO __asm__ ("BAR") ;
% gcc b.c -c && nm b.o
U BAR <<<<<<<<<<<<<<<<
0000000000000000 T call
% clang b.c -c && nm b.o
0000000000000000 T call
U FOO <<<<<<<<<<<<<<<<
%
This is minimized from glibc sources where FOO=strtol.
Most likely it's easier to fix this in glibc than to support it in Clang.</pre>
