It is not possible to build exfat-utils, ebuild simply fails, because it claims it cannot find a working C compiler. Therefore it is no longer possible to access large microSDXCs with Gentoo (sys-fs/fuse-exfat-1.0.1 fails with identical error). Reproducible: Always Steps to Reproduce: 1. emerge exfat-utils-1.0.1 2. 3.

While I don't recall the actual name, IIRC scons has a file of similar function to config.log. Attach it. Though, check 'gcc-config -l' first.
