0db1db10b8 Bug fixed: cg generated instructions like "and.l #2,a4", which are 
not allowed on the 68000.

accesses local non-register variables. So the ordering of the
patterns for regvar/non-regvar is no longer important.

cb0b2e08cf 1 - At RREMOVE also check the stack set aside for coercions. 
2 - When coercions unexpectedly need stack of part of the
stakpattern, discontinue this option.

c2a990768d The top of the stack, which is set aside for certain 
coercions is now saved with special routines.
This allows RREMOVE to check for registers.

408dacc2aa The stacking pattern for ldc C and 4 with highw(c)==0 was incorrect. 
The effect was that rand() from libcc/gen always returned
a 0.

445d52de66 Moved retar from ret.s to trp.s. 
trp.s needed it and is behind ret.s in the library.
When ret.s is loaded, it calls (via unknown) trp.s so
inclusion in trp.s should work.
