The goal with the OSGeo4W build is to not have to worry about linking anything but OSGeo4W libraries.  I thought that I was linking statically when creating liblas.lib, and boost-serialization and boost-program-options were statically linked and included.  It would seem this is not the case :(

Additionally, liblas_c.lib should be a static compile of everything in liblas.lib + the C API, and I wished to support the approach that Otmane had attempted and failed with.

I will do some investigation to see what might be happening.
