The test script I made just need the preprocessed files. So it actually 
doesn't see anything, besides the file names of preprocessed files. ie:

gawk -f signaltest.gaw main.i int.i otherfiles.i

The .i part of course being replaced as normally done in the makefile with the 
source files variable (like when passing the .c files to the compiler). 

You could modify the makefile so that it separates the compiling into first 
preprocessing, then run my script, then finish compiling from the 
preprocessed files (to avoid running the preprocessing twice).

Could you? It would be quite a bit better that way, but don't know how you'd 
do it...
