Comeau Computing offers
a C++ front-end (v18.104.22.168 as of July 2008) which converts C++ to C, which is
then compiled by a separate back-end. Currently, the Win32 port supports
VC++ 7.0, Borland, Metrowerks, MinGW, lcc-win32 and Digital Mars backends.
Comeau's C++ front end is also available on a wide number of other platforms, though support
for Win64 is not mentioned, and many of the web pages seem a
bit dated. The license runs $50.
I have not tried it out.
