This is a common and widespread problem. cc was generated with tables set up
too small, just to save space.. 
 
Unused .bss does neither require space on disk nor in memory.....One
point more Motorola should have thought about twice.

Sure, we. And we might offer help, see below.

Nice to talk to you all on the net, but I prefere more pleasant topics ;->.

Well known location. Reduction of conditional expressions kills the
compiler.

Correct.

Correct.

Correct.

A little help we can offer:

	1) Be warned:
	GCC produces position independent jump tables, which are
	to be compiled to "swbeg SIZE". "As" of most of SsysV68 releases
	is not able to compile them to correct object code.

	2) Once I built a crosscompiler on a SGI to compile gcc-1.37.

	3) We succeded in porting gcc-1.37 to SysV68R3V[56]. This 
	required port of gas, as the SysV-as was unstable.
	That of R3V5 was not able to compile jumptables,
	that of R3V6 does not always generate correct offsets
	for "link a6,#xxx".

	This port is not approved by RMS.

	This port is used for 18 month here and has successfully compiled
	GCC-2.0 and GCC-2.1 for sysV68. No major bugs are known.

	4) Executables for gcc-1.37,gas-1.38 and gdb-3.5
	are on "ftp.th-darmstadt.de:/pub/incoming/local_ports/sysV68/"

	5) Motorola has been informed both about the bugs and
	the port of gcc-1.37 available from us.

PS: You should be able to compile gcc-1.40 with our port of 
gcc-1.37 and gas-1.38.1.
