Old description:
> Missing gmpxx and gmp dependencies and use of --enable-auto-import for
> the linker.
New description:
Because of DL_IMPORT stuff in headers generated by Cython and
corresponding _ _ imp _ _ prefixes added in object files, farey.o cannot
be linked to farey_symbol.o (it could with farey_symbol.dll if we
generated it...).
The patch here does not include farey_symbol.h but directly declare the
prototype of the needed functions in farey.cpp, with the extern "C" stuff
but without the dllspec(import) stuff.
