Ahh, now I remember why the crt stuff is installed with -C.. It's because
c++rt.o is linked into dynamic and static libs, so doing a 'make install'
in csu/i386 used to cause a large scale relink next time around. Or
something like that..
I remember it was originally changed from "install -c" to "cmp -s ||
install -c" specifically to stop this problem. Changing it back to
${COPY} causes the problem to come back I think. If you really want to
preserve ${COPY} semantics, perhaps something remotely like this:
.if ${COPY} != -c
${INSTALL} ${COPY} -o ${BINOWN} -g ${BINGRP} -m 444 $i \
${DESTDIR}/usr/lib
.else
${INSTALL} -C -o ${BINOWN} -g ${BINGRP} -m 444 $i \
${DESTDIR}/usr/lib
.endif
Hmm.. in bsd.prog.mk, sometime ${PROG} is dependent on ${LIBCRT0},
sometimes not. It looks like this is incomplete, it should be dependent
on the static crt0 when linking static, and should still be dependent on
the crt0 object for all the other cases too, otherwise a 'make' would miss
an update to crt0.o.
Cheers,
