GCC 3 includes a standalone preprocessor that knows the "-traditional"
switch. I regularly use this preprocessor with this switch to preprocess
Fortran code, which all too unfortunately is very dependent on preserving
white space.

PS: The preprocessor that ships with gcc up to 3.0.3 contains a small bug
that make it insert line breaks under certain circumstances, at least when
the "-traditional" switch is used. This bug will be fixed in the upcoming
3.0.4 release.
