With the current bsd-port plus unrelated MLVM patches I got a clean  
Snow Leopard build.  It passed the MLVM regression tests.

I had to use GCC 4.0 as Michael suggested.

The 4.2 compiler is offering some porting resistance.  I put a patch  
into MLVM which copes with the new "printf" warnings it generates:

This patch is a bunch of lint-type fixes, and works fine on GCC 4.0.   
(Haven't tested on Solaris, etc, but s.b. OK.)  It's probably not  
worth the effort of pushing this patch upstream until we have a  
working GCC 4.2 build.

The current problem with GCC 4.2 is that when I build on x86_32, the  
JVM crashes in at least two places:  Under -Xint mode, the JVMG mode  
throws an assert on exit, and otherwise it throws asserts or crashes  
in compiler-related code.  The 64-bit version of the JVM appears to  
work, but I haven't exercised it much.

Since I'm chasing other problems, I'm going to leave GCC 4.2 alone for  
now.  If anyone wants to pick up this issue, help yourself to  
snowleopard.patch above.
