[Pyrex] Undefined symbol _Py_ZeroStruct

[Franck Pommereau]

I've tried to use my library from a pure C program, it works perfectly.
The link error occurs only when the library is loaded by the JVM.

Below is the C program. Notice that I pass null pointers for the
expected JNI objects, but this is no problem since they are never used.

Does anyone has ideas about linkage differences between a C program and
the JVM? I've tried to explicitly load in the Java program all the
library listed by "ldd _hello.so" and "ldd /path/to/libpython.so" but
this does not change anything.
