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.
Then I reran autogen.sh from upstream, deleted autom4te.cache and
repackaged, versioned, commented everything.
Patched spkg available at
http://perso.telecom-paristech.fr/~flori/sage/eclib-20120428.p0.spkg
Nevertheless, I think it would be better to repack a new release of eclib
including such changes to prevent the inclusion of the patches and the hg
history which make the spkg size explode.
Moreover, to make this work 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.

The -no-undefined flag should also be passed to libtool so that a shared
