[Jan Alonzo]

If the system has no pkg-config for SQLite, use the SQLite3 headers from WebKitLibraries as a fallback. Patch forthcoming.

Silly question, shouldn't you first try to use the headers that might come with the library you just found with AC_SEARCH_LIBS?
Or are you assuming that if there's no sqlite pkg-config file the only library you'll find is the one in WebKitLibraries?

Looks fine to me, although I'm not sure you really want to be depending on those headers.  Xan seems to have an objection though, so waiting for you to respond to that before marking r+.  Or rather, Xan can mark it r+ if he agrees.

Did we ever get a report that someone wanted to use sqlite3 but didn't have pkg-config files?

Yes. If there's no .pc file or there's no pkg-config binary, I'll just use what's in WebKitLibraries.

Consider this a report.
