exporting env var AUTOM4TE in autoreconf

[Peter Johansson]

Hello,

I have Autoconf 2.64 installed in `/usr/local/bin'
and Autoconf 2.63 installed in
`~/local/autoconf-2.63/bin/'
the latter is not in my path so `which autoconf' gives
`/usr/local/bin/autoconf'

In a project I wanted to check that the configure.ac still works with 
autoconf 2.63 so I issued
~/local/autoreconf-2.63/bin/autoreconf which gave the following output

autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force -I m4
autoreconf: configure.ac: tracing
aclocal.m4:16: warning: this file was generated for autoconf 2.64.
You have another version of autoconf.  It may work, but is not 
guaranteed to.
If you have problems, you may need to regenerate the build system entirely.
To do so, use the procedure documented by the package, typically 
`autoreconf'.
autoreconf: configure.ac: not running libtoolize: --install not given
...


IIUC, the problem is that aclocal here calls autom4te 2.64 and not 2.63. 
As aclocal has support for  environement variable AUTOM4TE I wonder if 
it would make sense if autoreconf exported this variable to something 
sensible. If the variable is already set there is no use of overriding 
the user's choice, but if it's not set one could set it to 
@bindir@/@address@hidden

Thanks
Peter
