GNU problems

[Mayan Wise - Israel]

Hi

There are two issues I have problems with

1. I use GNU make for '.c' , ' .cc' , '.cpp' , '.s'  files and when I try to
use pattern rules to separate them ( '%.obj : %.cc' or any other text
function on the prerequisite) it doesn't work and don't get into no rule.

2. It seems that text functions don't work in a ifeq( here ) or in the
prerequisites, is that so?

Hope you can help me with those issues.

thanks
