Pyrex generates C code, not C++ code, meaning you have to
compile its output as C, not C++. In other words, use
the command 'gcc', not 'g++'.

If the library really does have a C interface, there should
be no problem linking the resulting .o file with the library.

One caveat is that the .h file must be suitably #ifdefed so
that it can be processed as plain C. If not, you'll have to
tweak it or write an alternative one.
