It wasn't a batch file.  It's a data file that go32 reads directly.
You shouldn't have to do anything with it.

It's not supposed to.  The source would have #include <sys/...h> in
it.

They *are* dos programs, after all.  You must run them in a DOS box.
If you want a native OS/2 compiler, get emx.

crt0.o is in lib/ctr0.o under djgpp.  It's in djdev112.zip.  The
djgpp.env file points to it.

You need to run coff2exe to turn the gcc output into a DOS executable.
