$(MAKE) query

Thanks a lot for you responses. The -j option was ignored by make as I was using Sun make version 3.79.1.

I have one more query:

We are using recursive make for making the build and calling other makefiles in the sub directories using $(MAKE).

I just want to know whether $(MAKE) forks another process. If not than is there any facility that we can fork every sub-make as s separate process.

This would help us in reducing our build time as the total build process is currently taking 6 hours on Sun Solaris 5.9-sparc machine.

Any other suggestions are also welcome but the answers should be specific for solaris based system.

I just grepped the 3.79.1 sources for 'Ignoring' and 'DistributedMake',
and found only a line containing 'Ignoring VPATH name', so I wonder
whether this warning comes from somewhere else. If it were from use of
the $(warning) function in a makefile, I'd expect the message to be
[name of makefile]:[line number]:[warning text]
Could this be an altered version of GNU make, or some solaris make?
