includes, configure, /usr/lib vs. /usr/local/lib, and linux coders

[Steve Franks]

I believe someone has told me on this list that the proper way to
compile a linux program is to run configure
--includedir=/usr/local/include --libdir=/usr/local/lib.  Is that
correct?  I've got a bunch of linux weenies trying to tell me their
code isn't broken because I'm supposed to have headers where theirs
are.  They state that includedir is used by *their* project to locate
it's *own* headers, so they never bothered to wire it up in
Makefile.in....it gets ignored entirely.

I figured I'd better know what I'm talking about before I tell someone
they are 'wrong'.  Especially as it's usually me ;)
