Is there anyway to see what you code looks like after the preprocessor has done all the substitutions?
For gcc just use the -E switch
gcc -E
-E Stop after the preprocessing stage; do not run the compiler proper. The output is in the form of preprocessed source code, which is sent to the standard output.
That depends on your compiler. With gcc, you would use:
gcc -E source.c
Just a note about system headers (eg <stdio.h>): they are a pain when preprocessed.
gcc -E -nostdinc file.c or cpp -nostdinc file.c will not include expansion of system headers.
