Yes it looks tricky. It could very well be a regression as it compile with the C compiler and not the C++ compiler on my box with gcc 4.6.3 (gentoo). That being said gcc is very permissive and one day someone may decide to cut that one off. Would you believe that 2 days ago I accidentally configured octave with CXX=gcc-4.7.1 and I almost completely compiled it before being shot down by such a problem [octave is mostly c++]. Anyway you can certainly force sage's gcc by setting SAGE_INSTALL_GCC=yes before building sage.
