[perl #24155] [PATCH] pmc2c2 Makefile

[via RT]

# New Ticket Created by  Leopold Toetsch

Attached is a patch for easier testing of the new pmc compiler.
It probably requires gnu make, because it currently uses 
ifdef/else/endif to allow switching the old and new pmc compilers.

For now it should be rather simple to adjust these few lines. And 
finally they can go away.

Further changes:
- see the comment in Makefile.in WRT the fin: target
- removed some dependencies on generated pmc_*.h files

Comments welcome
