>Description:

When building pango on a -current sparc64 machine I noticed lots of messages
like this:

  GISCAN GLib-2.0.gir
/usr/include/sparc/mcontext.h:168: syntax error, unexpected identifier, 
expecting ',' or ';' in ' __asm volatile("mov %%g7, %0" : "=r" (__tmp));' at 'o'
g-ir-scanner: GLib: warning: 720 warnings suppressed (use --warn-all to see 
them)


>How-To-Repeat:

Just build pango-1.29.4nb2 and closely watch the log (the build does not
stop)

>Fix:
n/a
