how else could I implement those make rules?
I guess so called old-fashioned style of implicit rules would do:
e.g:
.SUFFIXES: .txt .tt
all: t.txt
.tt.txt:
cp -v $< $@
The .SUFFIXES part is not necessary, first off because you should use
SUFFIXES = .txt .tt (actually automake will throw a warning or an
error if you do this, can't remember) automake will recognize it and
do what-needs-to-be-done so that the generated Makefile is portable.
There are some issues with .SUFFIXES but can't remember what though.
http://www.gnu.org/software/automake/manual/html_node/Suffixes.html
"As you may have noted, the SUFFIXES variable behaves like
the .SUFFIXES special target
of make. You should not touch .SUFFIXES yourself, but use SUFFIXES
instead and let
Automake generate the suffix list for .SUFFIXES. Any given SUFFIXES
go at the start of
the generated suffixes list, followed by Automake generated suffixes
not already in the list."
But in the end, you don't even need to do any of this because
automake is clever enough to figure out that .txt and .tt must be
added in .SUFFIXES when it encounters the `.tt.txt:' rule.
