Bugzilla Bug 226195

I get this error message from configure:

configure: error: conditional "am__fastdepCXX" was never defined.
Usually this means the macro was only invoked conditionally.

I was remerging that package, and had not encountered this issue the last time.
The ebuild hasn't changed in a significant way, so I guess some eclass or my
update to portage-2.2_pre8 might be the cause for this. Perhaps some change to
elibtoolize, as the log looks a bit different around that point.

Portage 2.2_pre8 (default/linux/x86/2008.0/desktop, gcc-4.2.4,
glibc-2.8_p20080602-r0, 2.6.25-gentoo-r4 i686)

Upstream fix -r7052:7110

svn diff -r7052:7110 https://gnunet.org/svn/GNUnet/configure.ac

Upstream addressed this issue by including AC_PROG_CXX unconditionally. Given
the fact that subsequent (QT-related) checks seem work with C++ sources even
for platforms other than cygwin and mingw, for which it had been conditionally
included before, this seems a good solution.

Applied, thanks!
