Are we starting to depend on gmake being required again in the build
system...
I did not intend to do so.
%.pl: %.pl.in
-rm -f $@.tmp
echo "#!$(PERL)" > $@.tmp
sed 1d $< >> $@.tmp
chmod +x $@.tmp
mv $@.tmp $@
I forgot that this was not standard make syntax. Obviously, this code
is just arranging to have the right path for perl in the #! line at
the top of the scripts. I'd be perfectly happy with any decent
solution: (1) changing .pl.in to .pl_in and using a standard make
suffix rule, (2) having configure convert from .pl.in to .pl directly,
(3) anything else. Of course, configure also needs to find the right
path for perl; right now I'm just assuming it is in the standard
execution path.
(Of course a better question now is which vendor's makes worked with the
last release and is this a losing battle?)
It should be well known at this point that I think trying to use
vendor make is a waste of time, but I'm going along with it until
everyone else sees the light. :-)
