[Python-Dev] Making the CVS tree pass the -Wall test...

[M.-A. Lemburg]

While fiddling around with the _GNU_SOURCE define I found
that there are several warnings left in the current CVS
version which should be removed, I guess.

Here's the list I get from compiling the tree using -Wall
grouped by C file:

bufferobject.c: In function `PyBuffer_New':
bufferobject.c:174: warning: value computed is not used

[...many more of these... all referencing line 819]

In file included from ./mmapmodule.c:24:
../Include/Python.h:18: warning: `_GNU_SOURCE' redefined
./mmapmodule.c:21: warning: this is the location of the previous definition
[...looks like someone needed _GNU_SOURCE too ;-)...]
