Replace our ancient dtoa/strtod implementation with the gdtoa package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

Add __ldtoa(), a wrapper around gdtoa() to make it look like dtoa(). In support of this, add some MD macros to assist in converting long doubles to the format expected by gdtoa(). Reviewed by: silence on standards@ 2003-04-05 22:10:13 +00:00			`MISRCS+=_ldtoa.c glue.c`
