I looked through the cvs logs for make, and I couldn't see when make had
this bug, or when it had been fixed. I do recall Joe sounding uncertain
as to whether this was really the problem, as it is something he did a
few years ago. For example, maybe this was a bug in Solaris make that
he was remembering, and at the time he committed the change he didn't
realize that FreeBSD make was correct in this regard.
Anyway, if you are running 5.x, why not try it out? Try makefile like:
a=abc
all:
echo ${a:Mab}, ${a:Mabc}, ${a:Mabcd}
You should get an output like
echo ,abc,
,abc,
