powerpc-netbsd		almost-yes (there is an ABI mismatch with
   				our in-tree 2.95.3 that needs
   				to be addressed in the 3.3 code
   				base)


did anyone ever explain what the problem is?   to me, it always
manifested itself in programs passing va_list arguments failing
to compile.  the following patch appears to let this work...i'm
not entirely sure it's correct, but i appear to be able to build
general software with this change.  all it does it make the
va_list typedef not be a one-member structure in the gcc3 case,
but just the plain member.  this matches the GCC defintion...
