Hello,

this packages the the first patch of last/first email in this thread.

As described in the commit log (and previous email),
__sprint_r and __sfputs_r of (nano-)vfprintf.c
call fputwc.c's _fputwc_r.

While the vfprintf.c file is compiled for ELIX_LEVEL >= 1,
the fputwc.c file is only compiled with ELIX_LEVEL >= 4.

Solution: This patch ignores the _WIDE_ORIENT support in
__sprint_r / __sfputs_r unless ELIX_LEVEL >= 4.

It feels like the right solution but the ELIX description is
vague enough to be not sure.

Without that patch I get for ELIX_LEVEL == 1 (with nvptx)
a link error (missing symbol) for a code calling 'fprintf'
(with no wide char used).

OK? – If so, please commit. Otherwise, comments are welcome.

Tobias
