If you encased your SED script in a shell script that is passed the
source .c file and the target .hp files then only the makefile would
have to know the dependencies.  As a quick, dirty example:

In the makefile:

parse1.hp: parse1.c
	shell_script parse1.c parse1.hp

In shell_script:

rm $2
sed -f SEDscript $1 >$2

or whatever.
