Indeed, the 'm' modifier isn't implemented in newlib yet.  However, the
vfscanf code, while being a bot more convoluted than FreeBSD/NetBSD to
support small targets, is still based on FreeBSD and NetBSD.  It might
be possible to port the 'm' handling from one of them with moderate
effort.

Anybody here who'd like to do that?

Just send your patch to the newlib AT sourceware DOT org mailing list=20
and we're looking it over for inclusion.


Thanks,
Corinna
