Cannot import sage.libs.lcalc.lcalc_Lfunction

[jpflori]

Cygchecking the package shows that it looks for an inexistent libLfunction.so.
Indeed, this file is moved to libLfunction.dll on Cygwin to let Sage build.
But at runtime, it is the original .so file which is looked for (surely some DT_SONAME equivalent).
Letting libLfunction.so in place and symlinking it from libLfunction.dll seems more functional.

A better solution would to tell lcalc to build directly a .dll file on Cygwin (and .dylib on Mac OS X, etc.).
Updated spkg doing so at

Update lcalc spkg, modifying lot of the Makefile (that we already modify and which is not that nice) available at
http://perso.telecom-paristech.fr/~flori/sage/lcalc-1.23.p11.spkg

This will also need a Sage library patch.

I think its the last ticket needed to correctly build Sage and get a working version except for a few doctests.
It would be great to have it for 5.8, nobody wants to have a look?

I'm sorry, Jean-Pierre - I agree, but I simply have had no time at work to deal with my XP box (esp. since the 32-bit issue apparently is preventing proper rebasing, as discussed somewhere). I hope to try again over spring break in a couple weeks.
