Thanks for the suggestion, which, actually, I had already (only vaguely)
envisaged in my mind. As you can easily imagine, I'm not super happy with this
solution, since at run time comparing a basic_string with a basic_string, and
a basic_string with a "C"-string will be done in a way, comparing a "C"-string
with a "C"-string in another, inconsistent, way (for signed char type)
Don't you find this rather unsatisfactory?
Anyway, let's wait a bit for feedback from comp.std.c++...
