GPL.  not LGPL.

Sorry, I must have missed it.  I'll fix it now...

Not that I know of.  I generally just let mine evolve until I get 'em right.

I don't know if the C++ library will be all that simple to build

It will probably help if you run into any difficulties building the C++ 
library shared; prior to 1.5, libtool did not understand how to build 
things other than C code.
