>>>/usr/local/mpich-1.2.5.2/bin/mpif90 -c -I. -g __unsteady_ex.F -o unsteady_ex.o
"__unsteady_ex.F", line 965.2: 1515-019 (S) Syntax is incorrect.
<<<
The error is from mpif90 - not the preprocessor. Maybe its interpreting
the code as fixed form? Try adding '-qfree' to FFLAGS and see if it makes
a difference.
