Unfortunately, with my ancient version of GCC, I don't even get past
CHECK_LISP_OBJECT_TYPE in xgetptr:
.gdbinit:1197: Error in sourced command file:
No symbol "CHECK_LISP_OBJECT_TYPE" in current context.
Looks like PUBLISH_TO_GDB is not doing the trick here.
Anyway, with tricky macros such as PUBLISH_TO_GDB, I'd think that
going back to using variables whose type is the enum would be better,
don't you think? We could modify PUBLISH_TO_GDB to do that.
