# Without this, failed build products remain, with up-to-date timestamps,
# thus tricking Make (and you!) into believing that All Is Well, in subsequent
# make invocations:
.DELETE_ON_ERROR:
# Avoid accidental wrong builds, due to built-in rules working just a little
# bit too well--but not quite as well as required for our situation here.
#
# In other words, "make $SOME_TEST" is supposed to fail to build at all,
# because this Makefile only supports either "make" (all), or "make /full/path".
# However, the built-in rules, if not suppressed, will pick up CFLAGS and the
# initial LDLIBS (but not the target-specific LDLIBS, because those are only
# set for the full path target!). This causes it to get pretty far into building
# things despite using incorrect values such as an *occasionally* incomplete
# LDLIBS.
