strtold: New module.
* lib/stdlib.in.h (strtold): New declaration.
* lib/strtold.c: New file.
* lib/strtod.c: Consider USE_LONG_DOUBLE.
(STRTOD, LDEXP, HAVE_UNDERLYING_STRTOD, DOUBLE, MIN, MAX, L_,
USE_LDEXP): New macros.
(LDEXP, scale_radix_exp, parse_number, STRTOD): Adapt for
USE_LONG_DOUBLE.
(underlying_strtod): Remove function. Replace with some macros.
Re-add the code for a missing underlying function that was removed on
2013-02-19.

* m4/stdlib_h.m4 (gl_STDLIB_H): Test whether strtold is declared.
(gl_STDLIB_H_DEFAULTS): Initialize GNULIB_STRTOLD, HAVE_STRTOLD,
REPLACE_STRTOLD.

Description: POSIX compatible dprintf() function: print formatted output to a file descriptor Comment: This module should not be used as a dependency from a test module, otherwise when this module occurs as a tests-related module, it will have side effects on the compilation of the 'vasnprintf' module, if that module occurs among the main modules in lib/.
