[Vm-dev] Cog on linux

[Rob Withers]

(I am having trouble quoting Eliot's email as well.  Plain text is best)

I finally figured out how to specify to configure to use -m32 on the CFLAGS 
entries.  It is a part of the invocation of configure.

../../platforms/unix/config/configure 
CFLAGS="-m32 -g -O2 -msse2 -D_GNU_SOURCE -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 
 -DCOGMTVM=0" LIBS=-lpthread

I seem to have gotten past the problem with sqUnixHeartbeat.c and now I have 
a new problem:
