[PATCH] Make "all" depend on "info"

[PATCH] Make "all" depend on "info"

[Tom Tromey]

I've broken "make info" a couple of times now, because I sometimes
forget to run "make info" after modifying a Texinfo file.

I don't know why gdb's "make all" doesn't build the info pages.  I
suspect this was some Cygnus-local oddity back in the day.

This patch changes doc/Makefile.in so that the info pages are built by
"make all".  As a point of reference, Automake has essentially always
worked this way.  According to the Automake manual (I didn't
double-check) this is required by the GNU coding standards.

The first time I sent this patch, I mentioned that I wanted to look
into some existing bugs in bugzilla about missing "makeinfo".
However, today I tried and I discovered that BFD requires makeinfo,
and builds its info file as part of "all".  So, I think this change
doesn't worsen the situation for users in any way, and can simply go
in.

Fine with me, but did you verify the prerequisites won't cause the
manual rebuilt when not necessary?  IOW, does INFO_DEPS include
anything except the Texinfo sources?

Thanks.

No, it doesn't.  I'm checking it in.
