[Dbus-cxx-devel] Some potential backward compatibility patches

[<rya...@Te...>]

Hi again,
after today having dbus-cxx croak on "make" with gcc-4.2 after I tried
using my program at work (I use gcc-4.3 / gcc-4.4 at home), I made
these fixes for (slightly) older gcc versions.

dbus_cxx_configure.in_gcc_4.2_compat.patch
changes configure.in to additionally allow for the different includes
for tr1 in gcc-4.2 (as opposed to 4.1 which the current tr1 shared
pointer mode seemed to be based on)

dbus_cxx_tr1_smartpointers_for_gcc_4.2.patch
does the same for dbus-cxx/pointer.h

dbus_cxx_remove_default_template_arguments_for_gcc_le_4.2.patch
is simply an expansion of the "=nil" default template arguments in
several .h headers / .h.m4 headers, which seem not to be allowed
at all before gcc-4.3. I have #if'fed the defaulted version in for
newer gccs, although the expanded version would suffice, I assume?

Please consider them to increase backwards compatibility with older
gccs, a.k.a. those running in "stable" workgroup setups, and on OSX :)
They enabled me to build dbus-cxx on our old gcc-4.2 Ubuntu hardy.
