I'm trying to build my whole system with clang. The latest compile failure is on this package, however, GCC-4.9 doesn't compile it either: Compilation fails on both compilers due to "implicit declaration of function 'fstat'" -- and I'm not the only one, as I found this paste: http://pastebin.com/KkMy6QVf Adding the missing includes to $WORKDIR/xf86-video-intel-2.99.917/src/sna/sna_driver.c via the attached patch makes it compile fine, for me.
