changes to compile egcs-19991019 snapshot on MVS OpenEdition

[Michael Gschwind]

Here are two patches necessary to compile the 10/19 snapshot on MVS.  The change to flow.c is worrisome,
since some files now test for defined (HAVE_*logue) while flow.c tests for the actual value.  However,
the guard is necessary in flow.c to avoid an undefined reference to prologue_epilogue_contains,
although control would never reach that function anyway.

Some cleanup may be in order on this, maybe by removing the guards and providing a stub for 
prologue_epilogue_contains ?

        * flow.c (propagate_block): guard prologue_epilogue_contains with
        #if (HAVE_prologue) || (HAVE_epilogue).

        * basic-block.h (update_life_extent): remove trailing comma on
        enumeration type list.
