gfortran preprocessing


Is there a command line option to allow cpp to be a preprocessing front-end to gfortran. For example,
I am getting a "Warning: test.f:113: Illegal preprocessor directive"
and this code section contains preprocessing directives ...


#undef query
#ifdef query
     print *,'Input 2nd function file (y/n)?'
     read(5,'(a)')ans
     call caps( ans )
     if(ans(1:1).eq.'Y')part2=.true.
     if(part2)then
       write(6,40)'input filename for 2nd function file:'
       read(5,40) fv_function2
       write(6,40)'input filename for 2nd namefile:'
       read(5,40) fv_name2
     endif
#else
     part2=.false.
     mass= .false.
#endif
