This does not work in AMS-LaTeX:

	\begin{gather}
		\begin{multline*}
			a\\b
		\end{multline*}\\
		\begin{multline*}
			c\\d
		\end{multline*}
	\end{gather}

One can put an align environment inside gather, so why can't one do the
same with multline?  I have a need for this.

Another question: what is a simple way to have \ctagsplit@false in
effect in AMS-LaTeX?  \ctagsplit@true is set in amsart.sty, so not
including the file ctagsplt.sty does not work, and my current solution
of having a style file just to set \ctagsplit@false does not seem nice.

Thanks in advance for any and all replies,
