I haven't looked at the configure parsing code, but my intuition[1] is
that this what change something that can be done with a finite state
parser to something requiring a context-free parser. While such a
construct would be useful, I think that it massively complicates the
parsing of the configure file.

I do think that for some purposes, it might be useful to generate
configure files with perl (or even m4 ;-). While I never did that, I did
have similar configuration files on multiple machines to manage and was
always going to do that sort of thing anyway. Just another project I
never got around to.
