 Suprisingly, that replaces nothing and results in
 
 cc -c -DNDEBUG=1 -O2 -mcpu=ultrasparc -pipe -I/usr/include  -O2 hugs.c
 
 
 Nevertheless, the problem on NetBSD/Sparc64 seems to sit deeper as I get 
illegal instruction errors even when compiling hugs with -O0. Same problem with 
gcc34 on NetBSD/Sparc64. Hugs compiles fine with pkgsrc on intel/linux, though.
