sysv68

[Kaveh R. Ghazi]

Zack - I believe these bits should have been deleted when the
m68k-motorola-sysv port was zapped.

Ok for mainline?

		Thanks,
		--Kaveh

PS: There are a number of targets which don't even link cc1 (and
haven't for a few releases.)  I believe these should be additional
candidates for deprecation and removal.  If I determine which entries
are suitable for such a list, can we obsolete some more cruft?




2003-06-14  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

	* libgcc2.c: Delete sysV68 L_trampoline section.
	* config/m68k/mot3300-crt0.S: Delete file.
	* config/m68k/mot3300Mcrt0.S: Likewise.
