I have just learned :-( that snprintf is only part of C99, not of C89, despite being quite
widespread. Therefore, we cannot assume it to be available on systems using glibc2.0.x or
whatever not C99 compliant.

This is really too bad, since I think that using snprintf both greatly clean up the code and
reduces dramatically the memory used at run time when allocating the staging buffers.

I don't know if we can deal in some way with this problem, perhaps with libiberty or
whatever. Otherwise, forget about my later proposal and consider only the much more limited
fix for money_put::do_put of yesterday:

    http://gcc.gnu.org/ml/libstdc++/2002-03/msg00274.html

Ciao,
