This patch fixes a bug that shows up in GDB 3.5 when reading COFF
files.  The code that reads enum members doesn't stop when it should,
thus consuming symbols that should be read elsewhere.  In my system,
it showed up when debugging gdb failed; gdb complained because the
.bb/.eb (begin block/end block) symbols didn't nest properly.
