What does the last mean in practice? (definition of linking in this case?) If numpy and scipy are compiled with MingW gcc 4.*, then it cannot be used with the standard python? Or does it just mean we cannot combine fortran extensions that are build with MingW with extension build with visual studio? another example: would Matplotlib compiled against visual studio work with a new MingW compiled numpy? I guess that's what the ABI break would prevent? Since we will have to update MingW sooner or later anyway, I'm in favor of doing it. And given the comments on the mailing list about the Linux transition to gfortran, I expect that the transition will take some time. Thanks for your successful effort that installation on Windows was without problems for years for a user like me.
