Re: patch to lzip 1.23

Ahhhhh, I wasn't aware of the fact that it has to be specified as an argument not as a variable before the configure script!
My patch makes it possible to specify it with "CXX=my-gcc ./configure"

When compiling with mingw it produces lzip.exe, but the install target still tries to copy lzip, thus failing! AFAIK the only way to find out what extension a given compiler produces is to compile a minimal example and look at the output, which is what I have added to the configure script.

Klaus

You may already use a custom compiler with a command like this:

   ./configure CXX=your_compiler

See the output of "./configure --help" and the following message:

I don't use Windows, but as far as I know, lzip compiles fine there without
special handling of the .exe extension.

Best regards,
Antonio.
