But this has nothing to do with the original question.
We are not 15 years ago and we don't care about somebody else's past
investments (even if it sounds bad).

We have 2011 today and a range of compilers to choose from. Some of
them work, some of them don't. And there are new companies that start
new projects. They don't care at all about the history of each
particular toolchain - and frankly, they don't have to. This is the
landscape.

The SOCI and C++/Tcl libraries involve a good dose of metaprogramming,
operator overloading and basically every single funny language
feature. These projects were written for fun, so there was no limit
for what to use. :-)
The codebase contains only few workarounds for VC++ and none for g++,
as far as I remember.
In my experience the only problem that I had to face when porting from
g++ to VC++ was related to the contents of standard header files -
they tend to include each other in strange ways and differently on
each platform. But certainly, after some brushing it is perfectly
possible to compile even very complex code on both compilers.

BC++ is crap. If you have to target it, you can expect problems and I
can understand that the combination with the other two is problematic.

But then - maybe it is again the matter of experience and ability to
foresee problems before they come. I have been using C++ for
multiplatform development for the last 10 years, so my perspective
might be similar to the perspective of experienced Ada programmer who
does not have problems with GNAT. :-)

But then again, we are talking about new companies starting new
projects.
