Genmake2 doesn't have a -mods=  option? How so?

Hello Ed,

sorry, that I made so much noise. I think, our emails are now getting 
ahead of each other, but I have figured out how to fix linux_ifc (see 
my last email-posting).

More generally, I think that something like
$TOOLSDIR/genmake2 -mods=../code
should still work, that genmake2 should be able to figure out some 
default configuration, which it couldn't in my case. But maybe that's 
not your policy? I won't complain.

The nice thing about the .genmakerc is/was, that it made it possible to 
run genmake with the same options without specifying the options on the 
command line (source of error for me), but again, if that's a matter of 
policy, I won't complain.

The usage of genmake2 is probably not less intuitive than the usage of 
genmake, I am just used to the latter. I was refering to the code of 
genmake2, but I am not a bash-person (do you believe in reincarnation 
(o: ). genmake I could understand, and thus successfully manipulate, 
genmake2 is beyond my capabilities, but in the end, you don't want 
people to edit that file anyway, right? So, I won't complain.

I will now write a build_options file for Mac OS X (o:
