This won't help you. The problem is that neither the compiler nor the runtime
know about SCO Unix. If you'd a compiler and rtl supporting SCO unix, you could
easily cross compile from windows or linux or whatever. This is also the way how
new targets are added: first, the compiler gets support to target the new OS.
This compiler is a cross compiler e.g. linux -> sco. Then the rtl gets support
for the new OS. Using the cross compiler this rtl is compiled. Now the cross
compiler and the cross compiled rtl can be used to build a native compiler.
