Using the compiler switch -M2l insures that the compiler uses the large model
library for the standard C routines.  Assuming all of the your modules have
been compiled with -Ml2, there should be no model mismatches.

If you're using an ANSI compiler, be sure the standard C library prototype
header stddef.h is included (for correct malloc prototype), otherwise try
declaring malloc() in the modules which reference it:

char *malloc();
