great, this replacement (and also the one suggested by Armin with
create_string_buffer instead of c_char_p) seams to works (i.e., runs fine
on cpython).

this one is only in experimental code of pyopengl, so i won't bother much
for now.
the next issue is now that the array data types used by pyopengl are not
compatible with pypy ctypes: they are lacking (at least) _CData_input as shown
in the stack trace below.
any advice on that one?
should i try to fix PyOpenGL ArrayDatatype, or try to patch pypy's ctypes
function.py to work around that one?
thanks again,
renaud
