The errors are in the addition, or not, of a timezone string and
int8, float4 and float8 handling. A known issue with strtod() I think I read.
Don't know about int8.

For GCC as loaded from the SCO source CD's. ie gcc 2.95.3.
1. Add /usr/gnu/lib/gcc-lib/i586-pc-sco3.2v5.0/2.95.3 to your path.
ie PATH=$PATH:/usr/gnu/lib/gcc-lib/i586-pc-sco3.2v5.0/2.95.3:

2. Apply this patch to src/template/sco as directed by Larry.
if test "$GCC" != yes ; then
   CC="$CC -b elf"
