Trying to compile Python 2.4.1 under AIX 5.2 with the
native cc compiler.  When compiling the module
cjkcodecs the compiler will fail with these errors on
the source file Modules/cjkcodecs/_codecs_cn.c

building '_codecs_cn' extension
cc -DNDEBUG -O -I.

and so on.

This is happening because of the "hz" codec.  Due to
the way the source file uses the C preprocessor macro,
and the fact that the preprocessor symbol "hz" is
predefined as 100 on this platform, it is producing
invalid lecical symbols such as "100_encode".

The simple solution is to insert the following line in
the source file immediately before the first reference
to the name "hz":

  #undef hz

Fixed in r41647. Thank you!
