Here are some notes I wrote when switching from '-MD' to '-MMD': # Subsequent change: now '-MMD' is used. It was measured to improve # build speed by five or ten percent over '-MD'. It would be dangerous # to use with any preprocessor older than gcc-3.x's: the documentation # for gcc-2.95's preprocessor says it treats # #include <my_own_header_included_with_angle_brackets.hpp> # as a system file, which would be most undesirable [...] [because some third-party code uses angle brackets internally] _______________________________________________ Help-make mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-make
