I just use MSYS+autotools 2.68 to generate configure and config.in under src/gdb. I changed one file, see the change:
http://sourceware.org/ml/gdb-patches/2012-01/msg00591.html

The trick is that MSYS does not supply autoconf version 2.64, they have 2.63 and 2.65, but I'm not sure why 2.64 is skipped.

There are many python printer related function under the share folder of gdb, the simply one is "info pretty-printer", but there are many other commands.

If the gdb's own python script does NOT loaded correctly, when you run "info pretty-printer", gdb will say that there is not such command.
