[SciPy-dev] How to avoid arch specific compiler flags in scipy_distutils?

I've finally been doing some work updating the scipy & f2py debian packages and things are slowly progressing. The showstopper ATM, is the fact that the fortran sources are being compiled with architecture specific compiler flags ("-march=pentium4 -msse2 -msse ..."). I know that this is done automatically in scipy_distutils/gnufcompiler.py . Is there any non-intrusive way (i.e., from command line) to prevent that? José Fonseca
