No, ifc doesn't employ cpp, or invoke a gnu pre-processor. It has its own fpp which performs OpenMP translation. If you wish to use gnu pre-processing, you would use a Makefile or maybe a perl script, and the gnu pre-processor is run like
gcc -E -traditional -x c input > output.f
or
g77 -E input.F>output.f
If you set up your own pre-processing step, you must make the output acceptable as OpenMP syntax for ifc.
If you are looking for a pre-processor which works differently from gnu or Intel's, you must install it yourself. I'm not familiar enough with the fpp for which Sun made the source public, to know whether it does anything special with lines such as you quote.
You've posted several messages without saying what you want from these lines. You could try to find patterns for the -D option which will turn it into what you want, either with gnu pre-processing or with ifc's own fpp. Consider that the other pre-processors may also see $ as a special character. Possibly, an option such as -DC$=Cdollar might work.
If you wanted a pre-processor which conforms with Fortran committee standards (apparently you don't) there is Dan Nagle's COCO.
