[Coin-discuss] VolLp Example

[Laszlo Ladanyi]

Hello,

The problem is that libosi was compiled with support for reading gzip
compressed files, but Vollp was not. 

It is very important that the list of underlying libraries (those at the top
of the Makefiles) should be the same for building libosi and building the
final executable.

I have fixed the Makefiles and committed it into cvs. It shuld show up in the
tarballs tomorrow.
