GCC 3.1 fails to configure

GCC 3.1 will say warning messages in stderr if the directories search order for header files is changed from the default value. Because of this, it fails to configure XEmacs in my machine as follows: configure:6500: checking for X11/Intrinsic.h configure:6508: gcc -E -I/usr/local/include -I/usr/dt/include -I/usr/local/X11/include conftest.c >/dev/null 2>conftest.out cpp0: warning: changing search order for system directory "/usr/local/include" cpp0: warning: as it has already been specified as a non-system directory configure: failed program was: #line 6503 "configure" #include "confdefs.h" #include <X11/Intrinsic.h> Any ideas? I'm going to modify gcc-3.1/gcc/cppinit.c don't say such messages and rebuild GCC 3.1. -- Katsumi Yamaoka <yamaoka(a)jpl.org&gt;
