Re: gtk-doc version and configure.in breakage

[Damon Chaplin <damon kendo fsnet co uk>]

Alternatively we could just bump gtk-doc up to 1.0, and the old checks
will work again, won't they?


I don't really like using m4 macros for version checks, as it doesn't
usually give a nice explanation if you don't have the m4 file installed.
I prefer pkg-config files.
