I favor that too, if xmlto is available on all the platforms. Is it the case?

Yep, but it should be used

"for a program that might not be in the user's PATH"

It is not the case for tclsh, wish, xmlto... and itis useless to reproduce
a part o the user PATH. 

It is only needed, in our case, when the command is searched in the root 
user PATH, therrefore not in the user path.

As you can see those additionnal paths are for directories not in the casual
user's path.

I second that, too. Who use the cvs version on a platform with an older
autoconf? Moreover some bugs are fixed in versions above 2.50.
