IIRC MicroSoft adopted this convention (leading underscore) to support 
common library functions that are not part of the official standard.
(ISTR the practice itself is mandated by the C standard, but I am no
expert in this field).

Why it is not included as snprintf() in the newer versions of the
compiler - as witnessed by David Aldrich - is a riddle I can not
answer.
