  • mto: This revision was merged to the branch mainline in revision 4737.
  • Revision ID: john@arbash-meinel.com-20091012214427-zddi1kmc2jlf7v31
Py_ssize_t and its associated function typedefs are not available w/ python 2.4

So we define them in python-compat.h
Even further, gcc issued a warning for:
static int
_workaround_pyrex_096()
So we changed it to:
_workaround_pyrex_096(void)

Also, some python api funcs were incorrectly defined as 'char *' when they meant
'const char *'. Work around that with a (char *) cast, to avoid compiler warnings.
