Hi "brainf",

Your cygwin install doesn't include a full development environment.  It
lacks the headers that declare data structures for signal registration.
Those headers are probably available (or installable) within cygwin
since they are needed by a vast number of packages (not least of which
is bash).

So, some things that can be done are:

 1) figure out how to install those headers (probably a quick
    "apt-get ..." command but I don't know which package
    provides them),

 2) by hand, remove all instances of "sigreg.c" from the Makefile
    following the "make depend" step, or

 3) quit using the half-baked cygwin environment and run MITgcm
    on an actual Linux or Unix machine.

I recommend option #3.
