Hi,

There is a bug in the newlib scanf family implementation (actually, in
__svfscanf_r in libc/stdio/vfscanf.c) that causes it to read strings of
the form 0x0+ incorrectly.  Attached is a testcase that demonstrates the
bug on Cygwin.  I suspect the following change:
<http://sources.redhat.com/ml/newlib-cvs/2004-q2/msg00008.html>.
HTH,
	Igor
