[UDUNITS #QKV-165487]: udunits 1.12.4 bus error

C preprocessor directives like "#define VAR 1" are definitely not
standard Fortran: they are directives to the C preprocessor which
the Fortran compiler uses on it's input files before compiling them.

I suspect that the file "qscat3_tropics.f" uses directives like

include 'udunits.inc'

rather than directives like

#include "udunits.inc"

The former might be valid g77(1) but it is not standard Fortran
because there is no standard Fortran for including header-files.
The best that can be done is to use C preprocessor directives
instead of any Fortran "include" statements.

Try changing the directives to the C-form and see what happens.
