#1 Patches for building with recent GCC and FLTK
This patch is needed to compile the Emulator successfully with
recent versions of GCC and the FLTK library. It addresses the
following main issues:
* Renaming of filename_ext() to fl_filename_ext() etc, in line
with the renaming in FLTK 1.1.x (trivial);
* Removal of spurious braces in struct initialisations, about
which the compiler is more strict than it used to be (trivial);
* Various C++ obscurities about which the compiler is more
strict than it used to be (decidedly non-trivial :-));
* For obscure reasons involving the FLTK changes to configure.in
and subverting automake, it includes a couple of build-related
patches that I've had lying around for a few years. The only
interesting effect of this is that building in a separate
directory (even more separate than BuildUnix) now works.
When compiled with GCC 3.4.x or 4.0.x, this results in a working
poser. In particular, the miscompilation with GCC 3.3.x
described in
http://news.palmos.com/read/messages?id=153083
has gone away. If you are using GCC 3.3.x, you will likely want
to arrange for EmPoint.cpp to be compiled with -fno-strict-aliasing
in order to avoid this problem. Or use a more recent GCC. See the
URL above for details.

The patch has been updated with a workaround for the GCC 3.3.x EmPoint.cpp
problem. It turns around that it (most likely) was indeed a bug in that compiler,
so the updated patch detects this compiler bug and uses a different version of
EmPoint.cpp if the bug is present.
With this updated patch, compiling with GCC 3.3.x should also result in a
working poser, without any -fno-strict-aliasing makefile tricks needed.
