* libc/stdlib/Makefile.am: Added ldtoa.c to list of sources.
* libc/stdlib/Makefile.in: Regenerated.
* libc/stdio/floatio.h: Added suitable MAXEXP for long double.
* libc/stdio/vfieeefp.h: Added long double bit structures.
* libc/stdio/vfprintf.c[WANT_IO_LONG_DBL]: Added long double support.
[WANT_IO_LONG_DBL](isinfl, isnanl): New static long double routines.
(exponent): Changed expbuf to reasonable maximum instead of MAXEXP.
* libc/stdio/vfscanf.c[WANT_IO_LONG_DBL]: Added long double support.
* libc/stdlib/ldtoa.c: New file containing _ldtoa_r and
_strtold routines used for conversions between character
and long double.
