cygwin: ratpoints is broken again

[williamstein]

I just tried building the ratpoints package on Cygwin, and

gcc main.c -o ratpoints -I/home/wstein/build/sage-4.3.3.alpha0/local/include -Wall -O2 -fPIC -DRATPOINTS_MAX_BITS_IN_PRIME=7 -DUSE_SSE -L/home/wstein/build/sage-4.3.3.alpha0/local/lib -lgmp -lm -L. -lratpoints                                     
main.c:1: warning: -fPIC ignored for target (all code is position independent)                                             
./libratpoints.a(find_points.o):find_points.c:(.text+0x170): undefined reference to `__imp____gmpz_mul_si' 
BOOM!

Thus the fixed that got in from #7015 has been broken before it ever really got to live :-(.

So this ticket is to implement that fix again.

Here are a few changes to William's spkg:

• I renamed it to ratpoints-2.1.3.p0, which is the patch level that comes after ratpoints-2.1.3.
• Turned on the executable bits of spkg-install.
• Separate the changelog for ratpoints-2.1.3.p0 and ratpoints-2.1.3. The changelog now reads:

=== ratpoints-2.1.3.p0 (William Stein, 14 Feb 2010) ===
 * Include change to spkg-install so that build works on Cygwin,
   a fix that was in (trac #7015), and somehow got list.  See
   trac #8267.

=== ratpoints-2.1.3 (William Stein, 14 Feb 2010) ===
 * Evidently somebody updated ratpoints to 2.1.3 and didn't
   update the SPKG.txt.  Oops.

An updated spkg with the above changes is available at

The package ratpoints-2.1.3.p0.spkg includes some cosmetic changes on top of William's spkg. Building ratpoints-2.1.3.p0.spkg went OK on Cygwin (winxp1 on boxen.math).
