pre-processor wishlist ?

[Adam <adam at eax dot com>]

hello,
	I had this nice wish for 'gcc -E' to be able to do:

	I would want to be able to specify what kind of parsing
	it can do. So that say I first can have it process all
	#ifdef's, and then separately have it process all
	#defines and #includes.

	this would be great when:

	- i want to clean up file for sake of **readability**.
	it is pain to go thru file with dozens of ifdefs
	and try to find "live" code (emacs,xterm,xfree etc
	etc etc etc).

	- if I want to consolidate several files into one.
	so ideally I would want first remove all #ifdefs
	from all files. then I could grep out all #includes
	and put them on top and call remaining of all files
	together (I can't do that before removing #ifdefs
	as some includes might not apply for my configuration).
	this as well is useful in debugging and going over the
	source code.

	how does this sound? I don't think it should be hard to
	implement (few lines of code?)
