I'd like to wait to have a reaction from other people. I vividly remember 
my eyes falling out of my sockets when somebody reported success on cygwin 
without NO_MMAP. If there is *any* cygwin version which fixes it, we 
should rather make people upgrade, no?

I am not so sure about forcing people upgrade, but we may end up
deciding it is better not to have NO_MMAP as the default.  If
that turns out to be the case, I'd prefer to have something like
this instead:

diff --git a/Makefile b/Makefile
