[GRASS-dev] ctypes not working in 6.x, differences between 6.x and 7.0

[Markus Metz]

The stuff created in lib/python/ctypes differs between 6.x and 7.0,
the 6.x versions being rather messy.

The Make system in 6.x should be updated to clean up the mess,
particularly that z lib to avoid the following error on 64bit Linux:
/lib/libz.so.1: wrong ELF class: ELFCLASS32

IMHO, the solution should not be a hack that removes _libs["z"] afterwards.

sniplet from e.g. /lib/python/ctypes/vector.py in 7.0
