(You scared me!  bitfields.c has nothing to do with the problem :)

The problem is:

All the 's1's have been replaced by 'short'.  This is because of the
current argument on one of the gcc lists about how the demangler should
treat symbols that may be mangled but without the leading mangling
prefix for v3 mangling.

GCC folks, can we please get this fixed?
