Comment (by embray):
Possibly of interest for this patch--I'm currently working getting sage
building on Cygwin, and currently am stuck at fflas-ffpack with the
following:

I tested the branch in this ticket and still had this same problem. It's
a little mysterious, but I haven't deeply investigated it yet.
However, if I go into the build directory for fflas_ffpack and manually
run:
{{{
$ ./configure --prefix="$SAGE_LOCAL" --libdir="$SAGE_LOCAL/lib" --with-
default="$SAGE_LOCAL" --with-blas="$(pkg-config --libs cblas)" --enable-
optimization --disable-static
}}}
So ISTM it would suffice to remove the special section in `spkg-install`
for Cygwin which I guess is no longer required (why, I don't know). That
might as well be done as part of this patch.
