This is for gnumake-3.26. I previously posted the wrong patch.

re: patch to get parallel make to work

The problem is the following:
         
        + in decode_switches, you call decode_env_switches. So far so good.
        + after decode_switched, you call  new_environ () 
 
          this builds MAKEFLAGS and MFLAGS from the command line switches.

          however, if the parameter is a positive_int && == 'j' (i.e. -j) 
          then MFLAGS is set to -j 1

This has the advantage that it doesn't pass the parallel-ism to the child,
however....

	+ decode_env_switches is called again

Now that MFLAGS has ``-j 1'' in it, job_slots of over-written, being set
back to 1.

The fix I did is to just remove this check & to pass the -j value for the
current value of job_slots. However, to keep the previous meaning,
perhaps the check should first insure that job_slots has the default value
before resetting it to the default value?

I'm not certain what the intent was. Roland?
