from an obstack/bcache-managed macro table leaks memory.
* macrotab.c (macro_free, macro_bcache_free): Instead of asserting
that data is never freed in obstack/bcache-managed macro tables,
just leak the storage.
(macro_undef): If we're undefining a macro at exactly the same
source location that we defined it, simply remove the definition
altogether.
definition is the same as the previous one. Take more arguments
to allow the comparison.
(macro_define_object, macro_define_function): Pass more arguments
to check_for_redefinition.
* macrotab.c (macro_lookup_inclusion, find_definition,
new_macro_table): Same.
* macroexp.c (currently_rescanning, expand): Use `strcmp () == 0',
not `! strcmp ()'. This is a dubious improvement.
* macrotab.c (macro_lookup_inclusion, find_definition): Same.
* macrotab.c (macro_lookup_inclusion): Initialize `best_depth',
although it's not necessary, to avoid a warning.
