Hello all,
This is just a heads up.
I've landed a large commit to configure.ac recently and also Rico Tzschichholz has been assisting me with some changes to the autogen.sh script too modernise a bit.
Autogen.sh:
 We now run gnome-autogen.sh, so building Tracker from *git* will
 require gnome-common. This shouldn't affect those building from
 tarballs.
Configure:
 I've spent some time updating configure in a few ways:
 1. Now you can use --enable-minimal, and only tracker-store is built
   and command line utilities, everything else is disabled.
 2. All ./configure arguments have been updated to use $enableval and
   $withval. This fixes some cases where the --disable-* variant is
   used. This has also fixed some cases where the AC_ARG_ENABLE or
   AC_ARG_WITH 'if-not-given' was used incorrectly.
 3. There is now a --enable-tracker-extract (default is enabled), now
   it can be disabled.
 4. There is now a --enable-tracker-writeback (default is enabled), now
   it can be disabled.
 5. Summary now reflects what is built more concisely and is much
   smaller when using --enable-minimal.
 6. After running autoscan, ./configure now has more checks for PROGS,
   HEADERS and FUNCS that are being used.
 7. AC_USE_SYSTEM_EXTENSIONS is now used adding C extensions where
   available (like _GNU_SOURCE).
For most, these changes shouldn't affect you, but you never know :)
Any problems, let me know!
