Re: [RFA] Fix gdb/277 by separating types


Mr. Test-Bed choked on this pair of patches.  He died early in the
first configuration tested, in gdb.base/maint.exp.

There's a tarball at

  ftp://ftp.shout.net/pub/users/mec/gdb/20020510-drow-test.tar.gz

That includes gdb.log, the gdb executable, and the core file in it.
