adds the following: sscanf(3), <string.h>,
<ctype.h> wrappers; array, regex(3), stack,
queue operations; GDBM, SQLite, PostgreSQL, MySQL
database interfaces; HTML template engine (BASP);
Expat XML parser interface; x-y char plot; DOS,
CSV, Awk support; Libwebserver interface; RPN
calculator with <math.h> functions; and,
GTK+2 interface for GUI dialog.
