GTK 3 is the default, falling back to GTK 2 if 3 isn't available; you
can also say --with-gtk=2 to force GTK 2.

This is probably slightly nicer anyway, in that it specifies exactly
_which_ ANSI standard I'm talking about; but the main reason for
making the change is that it means I can now build the Unix puzzles
with clang.
It's not that clang doesn't _support_ -ansi; it accepts it just fine
on any command line that's actually doing some compiling. But on a
link-only command line, i.e. with only object files as input and no
sources, clang emits the annoying warning "argument unused during
compilation: '-ansi", and if you have -Werror as well then that
warning becomes an error.
You'd think there would be some makefile flags variable I could
nonetheless put -ansi in, but apparently not - automake passes CFLAGS
to both compiles and to link-only commands.
And you'd also think that surely I should be able to work around this
by having my configure.ac do a test link and stop trying to use that
option if it didn't work - especially since configure.ac already tests
a bunch of compile options to make sure they don't object to system
header files, after the time I found that a GTK header was
incompatible with my usual -Werror. But in fact, if I change that
AC_COMPILE_IFELSE to an AC_LINK_IFELSE, autoconf generates a single
compile-and-link command line, and hence does not expose the problem
using -ansi on link-only command lines.
Fortunately, -std=c89 does not generate this same warning from clang.
I don't know why not - surely the two options are more or less
equivalent - but it makes my build work again for the moment.

I'm going through all my projects and reworking them to avoid
depending on the monotonic integer-valued source control revision
identifier provided by Subversion, so I can migrate everything to git
without my builds and versioning breaking.
Puzzles's version number is now of the form YYYYMMDD.vvvvvv, where
vvvvvv is some string of source control information (currently still
the SVN-style "rNNNNN", but free to change in future). The date
provides monotonicity between my official automated builds, and the
second component is the one I'll be most interested in when people
send bug reports.

flags if gcc is in use - but _only_ if they don't lead to problems in
a test compile which includes all the system and GTK headers I'm going
to want. Ubuntu 13.04 includes a version of Pango which breaks at
-Werror -pedantic, so I can't unconditionally enable all the warning
flags I might want without breaking the build in ways beyond my
control.

Makefile.am, and there's a new mkauto.sh which builds a corresponding
configure script.
The old makefile has been renamed from 'Makefile' to 'Makefile.gtk',
indicating that the intended new _default_ approach is to use the
autoconf world. Makefile.gtk is provided as an emergency fallback in
case anything fails with the new stuff that used to work with it.
The new configure script does not support the same $(BINPREFIX) system
as the old Makefile did. However, as I understand it, it should be
possible to configure using --program-prefix="sgt-" (for example) and
then the binaries should all be renamed appropriately at install time.
The Makefile.am is quite painful. The Puzzles codebase relies heavily
on compiling individual object files multiple times with different the
cpp flags per build deliverable (program or library) and not per
source file. Solution: anything built with non-default compile options
has to go in its own little library. But that doesn't work either in
the general case, because as soon as you have more than one such
library linked into an application, Unix ld semantics bite you if the
objects in the libraries both refer to each other. So I ended up
building all those little libraries but not _using_ them - instead the
link commands for the programs needing those objects refer to the
objects directly, under the silly names that automake gives them.
(That's less fragile than it sounds, because it does _document_ the
names of the intermediate object files. But still, yuck.)
