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

        CC builtin-ftrace.o
    builtin-ftrace.c: In function ‘set_tracing_clock’:
    builtin-ftrace.c:197:14: error: declaration of ‘clock’ shadows a global declaration [-Werror=shadow]
    builtin-ftrace.c: In function ‘canonicalize_directory_name’:
    builtin-ftrace.c:350:53: error: declaration of ‘dirname’ shadows a global declaration [-Werror=shadow]
    cc1: all warnings being treated as errors

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