Generating a list of defined but unused macros

[Brian]

I've tried, unsuccessfully, to list out unused macros in my acsite.m4
used in the autotools. There is probably an easy way to do this but I'm
not all that familiar with m4.Any help would be appreciated 


Here was my latest unsuccessful attempt:

> unused:
>         @ if [ -e /tmp/unused_macros.log ]; then rm -f /tmp/unused_macros.log; fi
>         @ m4 -dta
> -R/usr/share/autoconf/autoconf/autoconf.m4f `ls *.m4`
> -o/tmp/unused_macros.log
>         @ grep AC_DEFUN
> /tmp/unused_macros.log | sed -r
> 's/m4trace:.*AC_DEFUN\(([A-Z_]*),\s|$|./\1/g' | sort | uniq >
> /tmp/unused_macros.log
>         @ cat *.m4 | grep AC_DEFUN |
> sed -r 's/.*AC_DEFUN\(\[(.*)\]\,.*/\1/' >> /tmp/unused_macros.log
>         @ echo Unused macros: "`cat
> /tmp/unused_macros.log | tr "\n" "\\n " | sort | uniq -u`"
>
