New description:
There are two problems with the current spkg on Cygwin:
* -lgmp should come after -lntl and -lpari, I fixed this in configure.ac
* the executables names in tests/Makefile.am should finish with $(EXEEXT),
fixed there as well.
* the -no-undefined flag should also be passed to libtool so that a shared
library gets built on Cygwin and for sage.libs.mwrank to be functional.
All of this is fixed in the 2012-08-24 release.
Try updated spkg at
http://perso.telecom-paristech.fr/~flori/sage/eclib-20120824.spkg
Moreover, to make this correctly compile on CYGWIN, presently you will
need, for instance, to manually create in {{{SAGELOCAL/lib/}}} a symbolic
link named {{{libpari.dll.a}}} to {{{libpari-gmp.dll}}} or use the PARI
spkg from #13333.
