I hope I don't ask a FAQ. If so, an URL would be appreciated. I've read here that someone could (should?) write #include <config.h> specifying a system header instead of the IMHO correct #include "config.h" As far as I know the difference is that in the first version system directories are searched but user directories in the second. Is this a kind of trick for something? Is is guaranteed that all compilers search the user path after the system path if the file was not found? oki, Steffen _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
