Printing texinfo to US letter size paper

[Jonathan Ryshpan]

I'm trying to print the documentation for GNU libtool.  The output of
texi2dvi is always for A4 size paper, even though the documentation for
the texinfo format says that letter size paper is the default.  Just to
be sure, I inserted the line "@letterpaper" at the start of the source
file (which is libtool.texi).  The output is still for A4 paper; it says
so in libtool.ps, if generated.

Why is this?  How can I get output for letter size paper?

Thanks:
