# 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 ...) works if this feature is present.

# since the bug is not annoying elsewhere.
