Re: preprocessor/7358: Changes to Sun's make Dependencies

[Andrew Pickin <PickinA at logica dot com>]

Sun's make works differently to Gnu's make.
This problem has nothing to do with gmake,
it can only be fully reproduced on Solaris 
running native make. [see SUNPRO_DEPENDENCIES]

The version of make which is distributed with Solaris 
stores the dependencies in a file identified by SUNPRO_DEPENDENCIES

Some of the functionality can be repeated for example

$ SUNPRO_DEPENDENCIES=foo gcc-295 main.c

and

$ SUNPRO_DEPENDENCIES=bar gcc-310 main.c

produce files foo and bar which are different.

The dependencies produced by Sun's make for object fiels 
are much more difficult to reproduce outside of the makefile.

This bug appears to have started in 3.0, but remains in 3.1.0
