(C++) tidying patch

[Jason Merrill]

This patch fixes two --enable-checking crashes, an error compiling
libgcc with strict prototypes, and an ungrammatical error message.

2000-07-17  Jason Merrill  <jason@redhat.com>

        * typeck.c (build_binary_op): Fix grammar in warning.

        * exception.cc (__eh_free): Fix prototype.

        * decl2.c (finish_decl_parsing): Handle TEMPLATE_ID_EXPR.

        * decl.c (pushdecl): Handle seeing an OVERLOAD in
        IDENTIFIER_NAMESPACE_VALUE.
