Having a portable 'locale_t' type is only part of what applications need.
They also need the corresponding functions. The following are specified
by POSIX:
is*_l
isw*_l
nl_langinfo_l
str*casecmp_l
strcoll_l
strerror_l
strfmon_l
strftime_l
strxfrm_l
tolower_l
toupper_l
towctrans_l
towlower_l
towupper_l
wcscasecmp_l
wcscoll_l
wcsncasecmp_l
wcsxfrm_l
wctrans_l
wctype_l
getlocalename_l
gettext_l
There are many more locale-sensitive functions, from mbrtowc to strtod.
POSIX does not have the corresponding *_l functions for all of there,
because they assumed that the programmer can use uselocale() to get
the same effect. But this does not work portably: Native Windows and
NetBSD platforms don't have uselocale(), and there is no way to implement
uselocale() in Gnulib. (We would have to override *all* locale-sensitive
functions, from mbrtowc over strtod to fprintf. This is not feasible.)
So, in order to fulfil the two use-cases from [1], we'll need many
*_l functions.

Let me start with the LC_CTYPE category and function isalnum_l.
