Message 244377 - Python tracker

Makefile.pre defines BASECFLAGS to include -Wunreachable-code. When building in the Linux environment available to me (GCC 4.4.6), compilation spews tons of warnings about "warning: will never be executed". According to this StackOverflow thread:

http://stackoverflow.com/questions/14591778/

that flag was always broken in GCC and was eventually removed in 4.5. Maybe we should dispense with it when building Python, at least unless requested by the user.
