 I hope this is the only problem currently but I'm not sure. In general I'm
very wary of using 2 different run-times inside the same process and here
we have at least 3 of them (2 DLLs + the main exe). Not to be pessimistic,
but I fully expect more trouble because of this in the future.

 Unfortunately the last mention of this (worthy) goal is from November
2004 so it doesn't seem to be very urgent. And doing it seems to imply
patching libstdc++ sources on gcc HEAD which is not an obvious thing to do
for a person external to the project (i.e. it's not obvious to get such
patches accepted).
