Thanks for that Alan. That confirms that CentOS and RHEL build autoconf 
against M4 1.4.5
 
This is a grep form an rpm2cpio unpacked SL5 autoconf rpm
find ./ |egrep m4f | xargs egrep 'frozen state file gen'
./usr/share/autoconf/autoconf/autoconf.m4f:# This is a frozen state file 
generated by GNU M4 1.4.8
./usr/share/autoconf/autotest/autotest.m4f:# This is a frozen state file 
generated by GNU M4 1.4.8
./usr/share/autoconf/m4sugar/m4sh.m4f:# This is a frozen state file 
generated by GNU M4 1.4.8
./usr/share/autoconf/m4sugar/m4sugar.m4f:# This is a frozen state file 
generated by GNU M4 1.4.8


Thus SL autoconf is built against M4 1.4.8 not M4 1.4.5 like upstream 
ans so I think that confirms a bug in SL.
The solution to the bug seems to be to build autoconf on a clean SL5 
install (containing the standard SL m4 rpm).

Now of course I am intrigued as to why the build system has a newer m4 
version on it at all??
