I'd like to see this fixed but I'm not on FreeBSD right now.  Any chance
you could write a patch?  I think there are two approaches, either (a)
figure out what incantation of BSD make is equivalent to «gmake -nspf
$file», or (b) use the -d switch to ask make what are the targets,
variables, and other things that _make-parseMakefile extracts.

g$words[1] won't work when $words[1] is "/usr/bin/make", and in any case
I'd be concerned about syntaxes that are valid to BSD make but not to
GNU make; there are bound to be numerous instances of that in the ports
tree.

Thanks,
