Not having access to a windows development platform I can't help you regarding
the actual problem with CAIRO_ENSURE_UNIQUE, but the negation warnings in
wideint.h are MSVC being overly panicky.  The loss of precision warning however
is valid, and in fact looking up the sole user of the function involved points
out a bug in either function naming or intention (cairo_fixed_mul_div_floor
does not actually floor; it's not essentially functionally different from
cairo_fixed_mul_div.)
