porting postgrers 8.3 on SCO 5.0.7

Hello there!

I trying to compile postgres 8.3 on SCO Open Server 5.0.7 but i got an error to compile cash.o:

gmake[4]: Entering directory `/u/erobles/postgresql-8.3.1/src/backend/utils/adt'
cc -b elf -O -I../../../../src/include -I/usr/local/include -c -o cash.o cash.c

gmake[4]: *** [cash.o] Error 1

i image the cause that is because the cast to long long doesn't exist on cc from SCO.
i'll be glad if you could help with that issue.
