Comment:

 Back to the error originally reported in this ticket: "`error:
 'MAP_ANONYMOUS' undeclared`". `MAP_ANONYMOUS` (which is called `MAP_ANON`
 on Mac OS X) is defined in /usr/include/sys/mman.h, but only if
 `_POSIX_C_SOURCE` is not defined, unless `_DARWIN_C_SOURCE` is also
 defined. python24 on Mac OS X 10.5 does not define `_POSIX_C_SOURCE` (try
 "`grep _C_SOURCE /opt/local/include/python2.4/pyconfig.h`") so ctypes
 works on Mac OS X 10.5, but python24 on Mac OS X 10.6 does define
 `_POSIX_C_SOURCE` (and does not define `_DARWIN_C_SOURCE`) so ctypes does
 not work on Mac OS X 10.6.

 The attached patch fixes this by defining `_DARWIN_C_SOURCE`. I don't know
 what other implications this might have. The patch also fixes #22418 by
 using the system's libffi instead of the ancient bundled one.
