[Guessing at where these changes are heading...]


btw It's probably not immediately obvious but the existing Makefile is
compatible with non-GNU makes including Microsoft's nmake.

It's a pain in the ass doing this but some of the things to avoid are:

 -include 
 include 

   This is part of why we use @MKINSTALL@ and autoconf to include
   MkInstall.in into the file.  Another reason is that it avoids
   providing targets that have no hope of working on particular
   platforms.

 $(wildcard *.c)
 gcc -M

   OTOH, if you wanted to add a script to generate dependencies or
   lists of files on your machine and these were automatically
   included in the distributed Makefile, that would be fine.

 ${FOO}

     $(FOO) is more portable


This is pretty important - there are still machines out there that
lack gnumake.  Even those that have it might have it under gmake so we
get a bug report and we send back one of those messages with 2 or 3
things to try.
