How do I control the space between the equation number and the right margin in the align environment?

A following example hacks into internals of align to add extra space that can be configured using \alignnumbersep:
\documentclass{article}
\usepackage{amsmath}
\newdimen\alignnumbersep
\setlength{\alignnumbersep}{10mm}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\math@cr@@@align@measure}
{\df@tag\fi\fi}
{\df@tag\fi\fi\kern\alignnumbersep}
{}{}
\patchcmd{\math@cr@@@align}
{\make@display@tag}
{\make@display@tag\kern\alignnumbersep}
{}{}
\makeatother
\begin{document}
\begin{gather}
\text{gather}
\end{gather}
\begin{align}
a&=b & c&=d\\
aa&=bb & cc&=dd
\end{align}
\end{document}

It turns out that whilst the trigger for my question was an unrelated matter (see tex.stackexchange.com/questions/134587/…), this question as it stands and what you have answered is something that I have wanted to know regardless, so I thank you for your answer. Sep 22, 2013 at 21:12
alignenvironment, or for all numbered displays?\gls{...}commands do (there is no example given, and i can't find any reference to that command in the companion), there's not enough information to give a meaningful answer to this question. perhaps it should be closed. regretfully downvoted.
