           Summary: Using GNU specific macro values without defining
                    _GNU_SOURCE
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)

          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

-D_GNU_SOURCE added to configure.ac

I've just checked out the weston code from git and some code in the master
branch like tty.c uses macros like O_CLOEXEC that requires _GNU_SOURCE to be
defined to be used. 

I've thought may be adding -D_GNU_SOURCE to CFLAGS in configure.ac would make
unnecesary to define it everytime GNU specific macros are used.
