Ok, good to know.  It would be nice if the -nomake <xxx> flags were
documented in configure -help.

I use -dont-process and run qmake myself because I don't know of any
other way to avoid the wall of gcc output and warnings.  I'm not even
sure -fast does anything.  I just put it in there because configure
-help listed it as an option and I like things to be fast.

I will do that after the current build finishes.

Is jom faster than mingw32-make -j2 on a dual core cpu?  I suspect it is not.
