That's an optimistic Wolf. About 1, changing extension of files to be
recognized by the compiler as C++ won't be so slow. <g> The only problem is
that AFAIK not all compilers use CPP as the extension, hope they are
configurable. About 2, probably several problems will be caught immediately
by the C++ compiler and the code changed easily but I expect that some of
the warnings require thought. We want to eliminate the cause of the warning,
not the warning itself. About 3, I'm surprised you think setjump/longjump
can be replaced quickly by try/throw/catch... maybe I need experience with
this task to have a decent estimation. About 4... better don't give an

Hmmm, it seems you welcome the idea of gcc on UNIX and MSVC for Windoze.
I've read in some forums that MSVC beats gcc on optimized code, any comment
on this?

Are you willing to come to the level of templates if necessary? What do you
think about trying to replace some preprocessor macros (the ones whose
conversion makes sense) to C++ inline functions?
