So inttypes.h is considered a GCC header than? And even if GCC mandates that
gcc-plugin.h should be the first header to include in a compilation unit, how
should this work in a autoconf projects which uses AC_CONFIG_HEADER, because
they also mandate that this header should be the first header to include (from
http://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers):

The package should ‘#include’ the configuration header file before any other
header files, to prevent inconsistencies in declarations (for example, if it
redefines const).
