Interesting. The only worry is that the run-time system and libraries
are all pre-compiled with the mingw gcc. So it's not clear to me that

Just a very general remark on this topic:
Mixing C and C++ is a highly delicate undertaking, see e.g. item 34 in

errors you see are probably related to initialization/shutdown of the
C++ runtime system, including construction and

However, I am using Cygwin now and that is where all
