Can you compile node.js under cygwin?

This program's configure is not cygwin-aware, apparently.  It sees something
that looks like Windows and it's heading toward msvs (Microsoft Visual Studio),
a Windows program, not a cygwin program.

I tried configure --dest-os=linux, and that mostly worked, but assumes ELF
binaries are being used, but cygwin uses PE, not ELF (so that Windows can
run the binaries linked with the cygwin library / runtime).  So the openssl
assembly files failed.  Using configure --dest-os=linux --openssl-no-asm got
past that problem but fails when trying to find /usr/include/sys/syscall.h,
someting not provided under cygwin.

I also tried not giving --dest-os (and it then wants to do the msvs stuff,
i.e., it treats it as Windows) and --dest-os=posix (which is what uname -a
reports under modern cygwin) to no avail.

So IMO node's configure needs to be adjusted, but how to do that correctly
is beyond my knowledge or the time I can invest.
