In the past we used the missing solution. >> Maybe sys/cdefs.h moved, and GCC 4.5 isn't aware of that yet? > > Well, `sys/cdefs.h` is included by `/usr/include/features.h` which is > *not* part of GCC.

Unfortunately, it did not work -- same error. That's normal. We unset the CPATH before building GCC due to ubuntu weirdness in the past. The problem is that ubuntu pusts `sys/cdefs.h` in a subdirectory of `/usr/include` for some reason. On Fedora, it can be found directly under `/usr/include`. The most dirty solution would be to simply symlink the directory. The proper solution would be to adapt the build system. We can add the directory to the include list in the easyblock when detecting ubuntu? Ward
