expansion in AC_CONFIG_COMMANDS

[Jason Roscoe]

Hi,
I'm trying to call awk from within the AC_CONFIG_COMMANDS macro in order 
to create a file called version.h.  But, I'm not sure if what I am 
trying to do is possible or whether I am just not quoting it correctly.  
No matter how I quote it, I can never get the appropriate command in the 
resulting configure script.

In configure.ac, for example  I have the following:

AC_CONFIG_COMMANDS([version.h], [echo version is "`awk '/MAJOR/ 
{major="$3"} END {printf "%d\n", major}' module.h`" > version.h])

This results in the following in 'configure':

   "version.h":C) echo version is "`awk '/MAJOR/ {major=""} END {printf 
"%d\n", major}' module.h`" > version.h ;;

This, of course, is not what I want.  Instead of major="", I would like 
the ending result to say major=$3 so.  Can someone provide a hint as to 
how I can achieve this?  Or, if there is a better way to do this I am 
also interested in suggestions.  Thanks.
