Hi, what is the appropriate test to know if we are using gcc3 or some other kind of compiler ? I need to do this for emacs: .if ${OPSYS} == "SunOS" CFLAGS+= -fno-zero-initialized-in-bss .endif but only if using gcc3 (this doesn't exists in gcc2). -- Manuel Bouyer <bouyer@antioche.eu.org> NetBSD: 26 ans d'experience feront toujours la difference --
