[Python-Dev] Any reason why CPPFLAGS not used in compiling?

[Brett C.]

I noticed that Makefile.pre.in uses the value from the environment variable 
LDFLAGS but not CPPFLAGS.  Any reason for this?  ``./configure -h`` lists both 
(and some other environment variables which are not really used either) so it 
seems a little misleading to have those listed but to not utilize them.

The reason I ask is I plan on having setup.py add the directories specified in 
both of these environment variables for compiling the extension modules.  It 
would be nice to be able to use the same values as used by the Makefile to 
build the core, but I can if I must just get the values directly from the 
environment variables themselves.

This should allow for the removal of the direct support for Fink and 
DarwinPorts.  It should also remove any hand-editing needed to get setup.py to 
pick up any non-standard library and header locations.
