'Twas brillig, and Maarten Bosmans at 30/04/11 14:25 did gyre and gimble:

Nice :)

I didn't even now you could call it with --enable-foo=no so I totally
agree that it's much more common to use --enable-foo or --disable-foo.
Not a great loss IMO.

> [PATCH 1/7] build-system: Simplify AC_ARG_ENABLE usage

I had to modify slightly due to XCB patch in my tree... nothing major
tho' (just the pkg-config stuff relating to xcb deps).

> [PATCH 2/7] build-system: Use AS_IF macro for configure output
> [PATCH 3/7] build-system: Move AC_DEFINE to separate line with AS_IF
> [PATCH 4/7] build-system: Move dependency error messages to outer scope
> [PATCH 5/7] build-system: Replace some more conditionals with AS_IF

As per patch 1 above.

> [PATCH 6/7] build-system: Rearrange database selection
> [PATCH 7/7] build-system: Small fixes

Pushed now :)
