[PATCH] wrap #ifdef for C99 around iswspace and mbrtowc in vfscanf.c

[litb_devel@web.de]

Hello List,

while working on my port of newlib, i got undefined references to those 
functions. That happened because i compile newlib using EL/IX level 1, which 
causes them not to be defined. 
I wrapped the portion that prints wide characters/strings with  
_WANT_IO_C99_FORMATS, just like it's already done while parsing the format 
string. Please be kind, it's my first patch/diff for newlib. :)
have fun, litb.
