The simplest method is to not output anything. Using the options
--no-emit-version and --no-comments would take care of that.

You could edit the message or use sed to replace the build OS and GnuPG
version strings with your choice, but you ruled that out already.

So, the final option is to build your own binaries. (see below)

It's much easier to edit config.h after ./configure and before make and
change the define of PRINTABLE_OS_VERSION to whatever you'd like it to be.

As your User-Agent string says you're on Windows, you'd most likely want to
consult Carlo Bianco's "Building GnuPG for Win32 using MinGW" page
(http://clbianco.altervista.org/gnupg/eng/gnupg.html).
