javaop.h type collision on AIX

	Appended is the end of the Make output before the failure.  The
include file lineage is java/parse.c includes a number of standard headers
which include <sys/types.h> which includes <sys/inttypes.h> which defines
int8.  int8 only is suppose to be typedef'ed if _ALL_SOURCE is defined,
which GCC does not.  I cannot find a source of that definition, but those
typedefs somehow are slipping through.
