In searching around for but 80803 I discovered that pushdecl_top_level
appears unused in the C FE. grepping under the gcc directory I find
definitions and uses in the c++ FE and separate def/use in the fortran
FE. In the C FE I only find a definition.
AFAICT this is a stale function and comment about objective C, which
presumably uses the pushdecl hook these days?
bootstrapping shows no regression. (I don't think this explains the
80803 problem)
ok?
