[help-texinfo] Page size

[Yang Zhang]

Hi, I'm trying to produce a PDF of the gprof.texi file in binutils-2.19
using texi2pdf:

$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.19.tar.bz2
$ tar xzf binutils-2.19.tar.bz2
$ cd binutils-2.19/gprof/
$ ln -s ../bfd/doc/bfdver.texi
$ texi2pdf gprof.texi
...

but I get the page size doesn't appear to be US letter:

$ pdfinfo gprof.pdf

For comparison, here's something US letter-sized:

$ wget http://people.redhat.com/drepper/nptl-design.pdf
$ pdfinfo nptl-design.pdf

How can I produce US letter-sized pages?  And/or, are there any
(reliable) tools for scaling pages so that they are US letter sized?
Thanks in advance.
