Garrett has implemented a -C flag to `install' that says to avoid copying
if the target compares equal with the source. We need to use this flag
in all Makefiles. I think the right method is:
sys.mk: INSTALL ?= install # same as now
bsd.own.mk: INSTALL_COMPARE ?= -C
bsd.own.mk: INSTALL_COPY ?= -c # replaces COPY
bsd.own.mk: INSTALLFLAGS ?= # user options
bsd.prog.mk etc: INSTALL += ${INSTALL_COMPARE} ${INSTALL_COPY} \
${INSTALLFLAGS} # sometimes more
Makefiles: ${INSTALL} [-c] ...
There is little point in putting `${INSTALL} ${INSTALLFLAGS} [-c]' in all
Makefiles. It mainly makes the commands longer. If different options
are required then plain `install' can be used. This would ignore any
special setting of INSTALL, but special settings have never really worked
anyway.
Makefiles have to use -c to install source files in case ${INSTALL_COPY}
is set to empty. Some currently use ${COPY} in more or less the right
places.
I have changed 81 Makefiles to use `${INSTALL}' instead of `install'.
Complain if you want anything different.
