What you need to do is compile the modules with the /Lp switch and link
with the os/2 libs (?libc?p.lib)

To produce a bound executable that runs on both os/2 and dos, you need to
produce an os/2 executable first.  the binder (bind.exe) then can be used to
produce the bound executable.

Hope this helps.  I know that the info is in the c5.1 ref man somewhere,
probably not easy to find, (*sigh*) but should be in the new section that
explains some of the new features of the c runtime for os/2.
