| No.  In fact the reverse - $(srcdir) = 1 - will hopefully be true
| everywhere.  (mk/library.mk still contains a hack to somewhat preserve
| old behaviour).

I look forward to our new masters.  Really.

| Should the TMP file be removed in the parser-clean rule?

Yes.  Thanks.

Fixed, I hope.  Does the revised $(RM) look OK?
