* lib/strtod.c (_GL_ARG_NONNULL): Remove; no longer needed.
Include limits.h.  Don't include string.h.
(HAVE_LDEXP_IN_LIBC, HAVE_RAW_DECL_STRTOD): Define to 0 if not defined.
(locale_isspace): New function, so that no casts are needed to
check whether *s is a space.
(ldexp): Provide an unused dummy if not available.
(scale_radix_exp, parse_number, underlying_strtod): New functions.
(strtod): Use them.  This implementation prefers to use the
underlying strtod if available, falling back on our own code
only to fix known bugs.  This is more likely to produce an
accurate result.  Also, it avoids the use of libm functions.
* m4/strtod.m4 (gl_FUNC_STRTOD): Don't invoke _AC_LIBOBJ_STRTOD;
no longer needed.  Invoke AC_LIBOBJ([strtod]); don't know why this
was absent, but it caused a test failure with coreutils.

Jim Meyering 42d1eda5dc many *.m4 files: improve m4 quoting 
99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
  -e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
  -e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
  -e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
  -e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4

The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job.  For more details, see
