You're right in mentioning that the fwprintf type functions should not
be used from cegcc, because their notion of FILE * comes from coredll
and is incompatible with newlib.
I knew that but failed to notice it when I sent this message.
However, there are quite a few other functions that don't have this
problem. Examples are (obviously swprintf), swscanf, wcstod, wcstol,
wcscat, wcschr, wcslen, .. . Again, see <tchar.h> .
A problem I see when inspecting this list is that e.g. wcstol isn't in
our cegcc.dll but wcslen is. Inconsistet.
My suggestion :
- Document why we don't have e.g. swprintf in the cegcc universe's
include files
- After the next release, try to figure out what to do about
inconsistencies like the ones I just found.

The "and ports" part of this sentence is probably very good advice, but
sometimes very (too ?) hard to accomplish.
