Don't make generated files read-only. That would bother too many people. However, do retain the ability to work when targets are read-only: remove the destination and temporary files before writing them (when generated via sed or echo), or by using the -f option for both cp and mv commands. Suggestion to use -f from Paul Eggert. * modules/alloca-opt, modules/argz, modules/arpa_inet: * modules/byteswap, modules/configmake, modules/fcntl: * modules/fnmatch, modules/getopt, modules/glob, modules/inttypes: * modules/localcharset, modules/netinet_in, modules/poll: * modules/stdbool, modules/stdint, modules/sys_select: * modules/sys_socket, modules/sys_stat, modules/sysexits:

# We need the following in order to install a simple file in $(libdir)
# which is shared with other installed packages. We use a list of referencing
# packages so that "make uninstall" will remove the file if and only if it
# is not used by another installed package.
# On systems with glibc-2.1 or newer, the file is redundant, therefore we
# avoid installing it.
