Decouple these modules from c-strtod. Nowadays it’s reasonable to
assume the C99 signatures for strtod and strtold. Programs that
require stricter adherence to C99 should also use the strtod and
strtold modules as needed, and we no longer need the
HAVE_C99_STRTOLD macro.
* NEWS: Mention this.
* lib/ftoastr.c (STRTOF) [LENGTH == 3]: Assume strtold.
* m4/c-strtod.m4 (gl_C_STRTOLD): Do not define HAVE_C99_STRTOLD.
* modules/dtoastr, modules/ftoastr, modules/ldtoastr:
(Files): Remove m4/c-strtod.m4.
(configure.ac): Do not require gl_C99_STRTOLD, which no longer
exists.
This is needed on HP-UX 11.11 with GCC 4.24; see Bruno Haible's report
<http://lists.gnu.org/archive/html/bug-gnulib/2011-06/msg00154.html>.
* lib/ftoastr.c (STRTOF) [LENGTH == 1]: Use strtof only if HAVE_STRTOF.
* modules/ftoastr (configure.ac): Check for strtof.
This is so that a program like Emacs, which needs only dtoastr,
does not have to bother with distributing and compiling ftoastr
and ldtoastr.
* MODULES.html.sh: Document these modules (ftoastr wasn't documented).
* modules/dtoastr, modules/ldtoastr: New files.
* modules/ftoastr: Now works just for 'float'.
(Files): Remove lib/dtoastr.c, lib/ldtoastr.c.
(Makefile.am): Remove ftoastr.h (not needed and no effect),
dtoastr.c, ldtoastr.c.
* lib/ftoastr.c (snprintf) [! GNULIB_SNPRINTF_POSIX]:
Implement a subset of snprintf here, by using sprintf safely.
* modules/ftoastr (Depends-on): Remove snprintf.
* lib/ftoastr.c: Also mention Loitsch's draft.
* lib/ftoastr.h: Require WIDTH to be nonnegative. This isn't
needed in the current implementation, but it might simplify
speeding up the code later.
* modules/ftoastr: Depend on snprintf; this improves portability.
Suggested by Bruno Haible in the same email.
Problem reported by Bruno Haible in
<http://lists.gnu.org/archive/html/bug-gnulib/2010-11/msg00242.html>.
* lib/ftoastr.c (STRTOF): Define to strtod if in a pre-C99
environment and strtold (and presumably strtof) are not available.
* modules/ftoastr (Files): Add m4/c-strtod.m4.
(configure.ac): Require gl_C99_STRTOLD.
