Re: Any basic cpp capability m4 cannot do?

Hi Daniel,

You may want to check cpp's ability with # to turn an arbitrary enclosed sequence of C tokens into a single C string that is properly quoted. Especially if said sequence already contains strings. This I found relatively difficult to imitate with m4.

My analysis suggests cpp and m4 share some 10 basic (non-trivial) 
capabilities, and m4 has some 15 basic capabilities that cpp cannot do. 
Examples of "basic capabilities" are: comment, define a macro, include a 
file, execute a system command, increment a number, etc.

My question: Can anyone suggest some basic capability cpp can do that m4 
cannot? Especially in the context of pre-processing C code.

I'm trying to anticipate what might happen on the next step of a 
conversion process, to anticipate something special cpp maybe does I've 
overlooked.

Thanks,
Daniel
