[found]: error during build of mork_helper, on illumos/xstreamos

[Gabriele Bulfon]

Libcups is broken, has a stupid bug when built under Solaris : the so file comes up referencing a main... Looks like this doesn't happen on Linux because of differences between linkers.
So when you link against libcups, and it's not a program but a shared library, ....

I faked a main in an object file, and it went on for that library.
...pity there are many in LO linking libcups....

I'm checking with illumos guys for any existent patch for libcups.

Thanks :)
