Make.exe for Cygwin

I have merged gnu-make-lo with upstream 4.1 and have binaries with the
following flavors:

64- and 32-bit Upstream 4.1 + my low-res stat workaround.
64- and 32-bit Upstream 4.1 + my low-res stat workaround + LO patches
(excluding depcache).

Didn't get a chance to do performance runs, but the binaries do work
and build LO fine (I only tried the 64-bit versions).

Let me know how you'd like me to share them for test runs before we
decide on which to settle.
If LO patches do not yield significant benefit then we can/should discard them.
