make handles suffix-rules differently from GNU make.
(SUFFIXES, .in): Remove.
(autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
Move the body of the old .in rule here.
## All the files below depend on Makefile so that they are rebuilt
## when the prefix etc. changes.
-SUFFIXES = .in
autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te: Makefile
-.in:
rm -f $@ $@.tmp
- $(edit) $< >$@.tmp
+ $(edit) $@.in >$@.tmp
chmod +x $@.tmp
mv $@.tmp $@
