- Add a little more glue for WIDE_DOUBLE; not done yet.
- s/def FLOATING_POINT/ndef NO_FLOATING_POINT/ to reduce diffs with FreeBSD.
- fix memory leak where each double formatted leaked 24 by calling __freedtoa()
appropriately. the new gdtoa keeps a list of memory chunks allocated by
malloc(), and it must maintained properly by calling __freedtoa() on the
results of __dtoa() Hi Klaus!
- in vfwprintf() make cvt return char * and convert it using __mbsconv(),
instead of having it return wchar_t *.
This should fix the memory leaks people have been reporting (eg. in top etc.)
