Re: My Windows build is much slower than Linux build. Any way to speed up?

FWIW, to not sabotage that goal it would be wise to try to restrict
dependencies of the build system to(*):

 http://gnuwin32.sourceforge.net/packages/make.htm
 http://gnuwin32.sourceforge.net/packages/coreutils.htm
 http://gnuwin32.sourceforge.net/packages/gawk.htm
 http://gnuwin32.sourceforge.net/packages/sed.htm

and plain C (like our concat-deps.c) -- at least for stuff that is used on
Windows. Thus maybe consider those options instead, when you want to add some
Perl or Python stuff that is used in the core build system(**).

Best,

(*) possibly: using only http://www.busybox.net/ instead of coreutils, gawk, sed.
(**) OTOH, we are bringing our own copy of Python on Windows anyway, but using
     it in the build is somewhat problematic both because its hardly a
     lightweight dependency for bootstrapping and probably a also a bottleneck
     increasing buildtime. So: meh.
