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

[Jeff Johnston]

Hello,

Unfortunately the WANT_IO_C99_FORMATS flag was added to keep additional 
formats like %C from
eating up space in the existing printf/scanf family.  Support for %lc 
and %ls was already in
place by then and so putting the logic under that flag may cause 
existing platform applications to
fail as only a few platforms have that flag turned on.

I have made a fix to the code to check the ELIX level flag that is 
provided in newlib.h.  If defined and
less than 2, then the code is #ifdef'd out.
