Hi, here is a patch to Gcc 2.7.2 to allow it to compile properly under SCO
Open Server 5 aswell as adding ELF binary support.
By default, this GCC will produce COFF binaries. To produce ELF binaries,
compile with -melf. If you are compiling library modules to build a
shared ELF library, use -melf -fpic. When you create the actual shared
library, use -shared.
I hope this helps.
