I've got following error when compiling on Fedora 16:

CC builtin-ftrace.o
builtin-ftrace.c: In function âset_tracing_clockâ:
builtin-ftrace.c:197:14: error: declaration of âclockâ shadows a global declaration [-Werror=shadow]
builtin-ftrace.c: In function âcanonicalize_directory_nameâ:
builtin-ftrace.c:350:53: error: declaration of âdirnameâ shadows a global declaration [-Werror=shadow]
cc1: all warnings being treated as errors

Fedora 17 seems to be ok.. strange ;-)
