[ANN] Windows builds no longer horribly slow

[Michael Stahl]

hello developers (and especially tinderbox maintainers),

on master since a week ago, builds with a native Win32 make should work
and are substantially faster than the old Cygwin make, both for
from-scratch builds and incremental rebuilds.

you can have a faster Windows build too, by using the following file:
http://people.freedesktop.org/~mst/make-85047eb-msvc.exe

and adding a line to autogen.input:
MAKE=C:/path/to/make.exe

(or just copy it to /opt/lo/bin/make)

note: this only works on master; release branches for 4.3 and older
require Cygwin make.

for details on how to build GNU make from source, and how much speed-up
to expect, see:
