--- Comment #4 from Stas Sergeev <stsp at users dot sourceforge.net> --- Jakub, people use "cc -E -Wp,-P $CFLAGS" as a generic preprocessor. $CFLAGS is needed to specify the includes, but all other options do never affect -E. But if CFLAGS contains -g3, you suddenly can't do that! > -g3 enables -dD Not letting people to use "cc -E -Wp,-P $CFLAGS" as a generic preprocessor, is a very bad idea. If -g3 enables -dD, then perhaps -P should disable it?
