Thanks!  That should certainly be helpful.  In the meantime, I found a way
to do import by including them in the .def file.  Here's a couple of example
.def files;

; os2term.def emx 0.8h def file
NAME os2term NOTWINDOWCOMPAT NEWFILES
DESCRIPTION 'TERM 0.0.1 by Phil Crown 1994'
IMPORTS p_transfer      =  P.p_transfer
STACKSIZE 0x50000

; giovio2.def emx 0.8h def file
NAME giovio2 NOTWINDOWCOMPAT NEWFILES
DESCRIPTION 'OS/2 2.x 32-bit serial example'
IMPORTS ComClose        = GIO2.ComClose
IMPORTS ComGetDCD       = GIO2.ComGetDCD
IMPORTS ComGetHandle    = GIO2.ComGetHandle
IMPORTS ComOpen         = GIO2.ComOpen
IMPORTS ComRX           = GIO2.ComRX
IMPORTS ComRXEmpty      = GIO2.ComRXEmpty
IMPORTS ComRXPurge      = GIO2.ComRXPurge
IMPORTS ComTXChar       = GIO2.ComTXChar
IMPORTS ComTXString     = GIO2.ComTXString
IMPORTS p_transfer      = P.p_transfer
STACKSIZE 0x50000

Add the .def file to your makefile, and create a prototype for each function
in a header file.

I haven't imported all the functions, but I add them as I need them.
