It's a Lenovo T400 (Intel P8400 - 2.26Ghz Core2Duo with 2GB RAM). I
repeated the tests and tried buiding gsl both in a FreeBSD VMware
guest on the laptop and natively on my desktop (3.2GHz P4 with HTT)
and it looks like the culprit is cygwin.
Cygwin VMware Desktop
spkg-install real 21:34 3:34 4:27
spkg-install user 14:06 0:35 3:22
spkg-install sys 12:28 2:45 1:02
spkg-check real 8:03 2:04 2:46
spkg-check user 5:36 1:04 2:25
spkg-check sys 4:11 0:57 0:21
The user/sys times in VMware look dodgy but I checked the real times
against my watch. In all cases, there's no '-jN' on the make.
Talking to some other people, apparently fork()/exec() and I/O are
really slow on cygwin - which means that anything using GNU autotools
and libtool is really stuffed.

I also thoroughly recommend replacing Windows with whichever Unix
variant you prefer.
