# Work around a bug in GNU Make 4.3 and earlier, which implements $(info MSG)
# via two system calls { write (..., "MSG", 3); write (..., "\n", 1); }
# which looks bad when make -j interleaves two of these at about the same time.
# Later versions of GNU Make have the 'notintermediate' feature,
# so assume that $(info ...) has the bug if this feature is absent.
# The workaround arranges for 'MSG' itself to end in newline;
# although this follows every message by an empty line,
# that's better than the interleaved output.
