[MITgcm-support] how to build the mitgcm code on cygwin?

[Dimitris Menemenlis]

Hi Ed, I have a full installation of cygwin but there is no "ucontext.h" header 
file anywhere.  So I get the same error message as Brainf does.  Shall we 
exclude sigreg.c by defining a TARGET_CYGWIN flag in the cygwin_ia32_g77 
build_option?  Is there a better way to do this?
