3. The config.status scripts generated by the configure scrips
I have tested are not working (all Makefiles end up empty), but
I suspect that's some issue between autoconf and dash. So far it
has worked to run ./config.status from plain old non-64-cygwin
between configure and make.
I made a first attempt to build emacs. I had the same problem as
Peter with all Makefiles being empty. In addition, the configure
test for mktime (attached) fails; CPU usage spins up to 25% (one
core), and the program has to be killed from the Task Manager.

Oh well. I don't know how to "fix" this, other than by ripping out
the entire localtime/mktime implementation and replacing it with
something new.
The reason here is the testcase itself:
[...]
So what it does is calling localtime with a time_t value set to
time_t_max. That's 0x7fffffff on i686, which manages to do the job in
less than 60 seconds. On 64 bit, time_t_max is 0x7fffffffffffffff.
That's roughly 2^32 times bigger than the 32 bit value, but the 64 bit
CPU isn't 2^32 times faster, unfortunately.
