Tools for macros expansion?

[Aleksey Yakovlev]

Hello,

I have to work with a somebody-else makefile, which contains multi-line macros with rules inside, like:

define F
$(ABC)/$(1)/$(2)/$(3)/$(4): $(DEF)/$(1)/$(2)/$(3)/$(4)
    ....
endef

which are expanded in $(foreach) loops. 

I'd like to look at this makefile with all these macros expanded... Are there any tools for that?

It would be nice to have an option in the GNU make, which does just that. Do you, GNU make developers, by any chance plan to add such an option? 

It'd be a great step forward...

Thanks,
Alex
