That is because C is passing by value and Watcom F77 is passing by
reference (i.e., effectively a pointer to the value).

You can override behaviour with pragmas (non-portable) or declare
the C stuff with * on the args so that is sends and receives pointers,
which will work with F77 in Watcom (and many other compilers).

THe Watcom Help and examples will provide details for pragmas and
for mixed language declarations.
