One other thing -- how about if we just remove the 'chmod' entirely?
If the source is readonly, that'd make the destination readonly.
Plus it wouldn't bother people who prefer to have read-write files,
and it'd save a command and a line of 'make' output.
An even shorter possibility would be:
alloca.h: alloca_.h
cp -f $(srcdir)/alloca_.h address@hidden
mv -f address@hidden $@
This relies on 'cp -f' and 'mv -f', but that's universal nowadays, no?
(If not, we could autoconfize it.)
