Well the relevant code is:

.PRECIOUS: ${MID}/%.NRLIB/code.o
${MID}/%.NRLIB/code.o: ${MID}/%.spad
        @ echo compiling $*.spad to $*.NRLIB
        rm -rf ${MID}/$*.NRLIB
        @ (cd ${MID} ; \
           if [ -z "${NOISE}" ] ; then \
            echo ")co $*.spad" | ${INTERPSYS}  ; \
           else \
             echo ")co $*.spad" | ${INTERPSYS} >> ${TMP}/trace ; \
           fi )

Logically removing old file is the first step of compilation. But
because of '@' char make does not echo the compile command, so you
get the output as-is.

BTW: I would write the above as:

${MID}/%.NRLIB/code.o: ${MID}/%.spad
        rm -rf ${MID}/$*.NRLIB
        echo ")co $*.spad" | ${INTERPSYS}  ${COMPOUTPUT}

with COMPOUTPUT beeeing ">> ${TMP}/trace" if we want silent
compilation and "| cat" if we want all messages. Note that
once we remove '@' char the first echo command is useless, since
the second line contains requested information.
