Ouch, that's against the requirements of the C, C++ and POSIX standards...

Is

OK, but it will involve major surgery - all those std:: prefixes to isXXX
will have to change, so will the section in boost/regex/config.hpp that
undef's the macros to get at the C API's.  Are you completely sure that
there are no real declarations?

I'm going to busy for a bit, so go ahead and make the changes if you want -
Oh and don't forget the config test program :-)
