We've been cleaning up our application and generalizing
our makefile on a Sun 3 (with SunOS 4.0.3). I'm wondering
about the use of certain Sun makefile features that may
not be portable to other target architectures, such as
Concurrent Systems, Silicon Graphics, VAX ULTRIX, etc..
Some of the Sun makefile features are found in the GNU
version of make (available from the Free Software Foundation)
and derived from AT&T System-V.3 of make. I don't have
either version of make around so I don't know what features
come from where and what are Sun only features.
Given all my uncertainties about make, I'm posting a survey
that I will post the results of in 2-3 weeks. I'm also asking
what nice portable features of make you use that make life
easier for you. An example of a nice feature would be automatic
dependency generation of all the include files via cpp(1) or
using the Sun .KEEPSTATE target.
BTW, an interesting article on make can be found in
SunExpert Magazine, April 1990.
