Witness the following typescript:

$ cat m4.txt

define(`echo1', `$*')

define(`echo2', `$ <at> ')

define(`foo', `This is the macro `foo'.')

#traceon

echo1(foo)

echo2(foo)

$ m4 m4.txt

#traceon

This is the macro This is the macro foo..

This is the macro foo.

$ sed 's/^#//' < m4.txt > m4_with_trace.txt

$ m4 m4_with_trace.txt

m4trace: -2- foo

m4trace: -1- echo1

This is the macro m4trace: -1- foo

This is the macro foo..

m4trace: -2- foo

m4trace: -1- echo2

This is the macro foo.

Sorry, what was confusing me was that the trace information is interspersed with the output. I.e.,

m4trace: -2- foo

m4trace: -1- echo1

This is the macro m4trace: -1- foo

This is the macro foo..

Blue is the real output and red is the trace. I was reading it like

m4trace: -2- foo

m4trace: -1- echo1

This is the macro m4trace: -1- foo

This is the macro foo..

I am attempting to install GNU m4 because I need it for Autoconf which I need for Flex which I need for Art and Bison for which I need it for cflowd (utterly ridiculous), Anyways when I try to do a ./configure it reports that it cant find itself. When I do a sh ./configure it goes through the files, but then when I try to do a make, it says can not find autoconf!!! That’s the whole reason why I am installing this.
