* Makefile.in (c-exp.tab.c, m2-exp.tab.c): Filter out bogus extern

declarations of malloc/realloc/free that are inserted by some
versions of yacc.
* m2-exp.y:  Prevent conflicts with TRUE and FALSE tokens by
#undeffing them.
* xm-rs6000.h:  Declare malloc/realloc/free appropriately.  Yet
another decl of strdup (this really ought to come from libiberty.h!).
