cpphash.c (collect_funlike_expansion): Make "# is not followed by a macro argument name" a pedwarn, not an error.
* cpphash.c (collect_funlike_expansion): Make "# is not
followed by a macro argument name" a pedwarn, not an error.
Preserve the # in the output. Suppress the warning if lang_asm.
* gcc.dg/dg.exp: Scan .S files as well as .c files.
* gcc.dg/20000510-1.S: New.
