This package is fundamental to hugs.


A small note: From lang/hugs Makefile:

# The default -O2 breaks the interpreter producing strange internal errors
# at run time.
.if !empty(CC_VERSION:Mgcc-4*)
CFLAGS+=    -O0
.endif


This does not work as expected. A line from the compilation phase:

gcc -c -DNDEBUG=1 -Wno-error -O2 -march=ultrasparc -pipe -I/usr/local/include 
-I/usr/include -O0  -O2 hugs.c



-O2 -march=ultrasparc -pipe comes from mk.conf. The final -O2 is set in various 
configure scripts as OPTFLAGS. I set OPTFLAGS to "" in these configure scripts, 
but I still get the illegal instruction. Hence, this does not seem to be the 
core of the problem.
