I think this is an (undocumented) feature. You should
_NEVER_ rely on _fixedpath returning the same length as
the string you feed in. IIRC, it internally calls 
_truename(), and that one prepends the current working directory
if it is not there, so you get a fully qualified pathname. 
Better use
 char fixed_name = (char*) malloc(MAXNAME);
(I think MAXNAME is the maximum len including
drive and path, cross check that).
