Trio is a highly portable set of string functions focused on its *printf() clones. The printf() formatting is compatible with ANSI, BSD, GNU, and most of the C9X specs. The scanf() parts are incomplete.

Added autoconf integration, fixed '%m.nf' output
(previously trio did not treat the width properly
in all cases), added explicit promotion for the
scanfv family, fixed more C++ compilation warnings.
