The core issue for smart_linker is the problem that occurs if the source
list includes two of C++, Fortran, D. If only one of them is there plus
possibly C then there is little problem.

So the problem to solve is how to link an executable where there are
source a.f, b.cpp and c.d. I actually think this may be close to
undecidable given the need to support Windows, OSX, Linux, FreeBSD,
OpenBSD, etc. It may thus be sufficient not to support this case. The C
++ + Fortran case is already a problem.

The revised D tooling in default/tip of SCons_D_Tooling, is already
working a lot better that the hack there was previously. All fully
tested on Linux and OSX.I guess I will have to steal a Windows machine
and set it up to test so I can create a pull request and avoid the
hassle of last time. But these D tooling changes really need to get into
a released SCons.

The question is can there be breaking changes in a minor revision, 2.3 →
2.4
