[cctbxbb] compilation errors under gcc-4.7

[Luc Bourhis]

Hi Justin,

do you need those statistical tools that fail to compile? To be specific, Python wrappers for the Student-t distribution. If not, then the easiest solution for the short term would be to disable the compilation of those on gcc 4.7. We already avoid compilation for gcc 3.2 iirc.

Best wishes,

Luc
