# If our install destination is case-preserving, but case-insensitive
# then we do filesystem comparisons in lower case to make sure that
# we always refresh the target when needed. In general we don't
# want to do this, otherwise things like _exit.2 -> _Exit.2 get
# installed on each build even when they don't need to. Note that
# the CASE_INSENSITIVE_DEST macro is currently not defined anywhere,
# and the expansion does not really work because of make(1).
