Comment:

 The build of scipy doesn't respect CFLAGS and CXXFLAGS variable, but mixes
 them. This is what I have set:

 CXXFLAGS="-O2 -pipe -march=core2 -frecord-gcc-switches -mssse3 -mcx16
 -mmmx -g -Wmissing-include-dirs -Wenum-compare"

 CFLAGS="-O2 -pipe -march=core2 -frecord-gcc-switches -mssse3 -mcx16 -mmmx
 -g -Wimplicit-function-declaration -Wmissing-include-dirs"

 where

 -Wmissing-include-dirs is only valid for C/C++

 -Wimplicit-function-declaration only for C

 -Wenum-compare only for C++

 which gives you following warnings during compile if Flags aren't
 respected

 cc1plus: warning: command line option "-Wimplicit-function-declaration" is
 valid for C/ObjC but not for C++

 numpy-1.4.1

 scipy-0.8/0.72 (gives same)

 gcc-4.4.4

 I will attach the build.log as well as a summary on the system.
