I'm running GNU make 3.62.
 
It would be real nice if you could specify the number of job slots
via an internal Makefile variable.  i.e.  In Makefile setting "JOBSLOTS = 4"
would be equivilant to running "make -j 4".  The same for the -l switch.
 
Also, having an "else if" conditional key word would greatly simplify
nested conditional "if" statements.

Another good idea would be to have operators for conditionals.  Such
as:

	ifdef HAVE_CURSES && ifdef HAVE_TERMCAP
		libs = -ltermcap -lcurses
	endif

and

	if OSVERSION < 411
		missing = strerror.o
	endif

Basically, the full range of "standard" CPP syntax is what I'm
suggesting.
