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).
