locale independant strto* missing (as well as their wchar variants)
0%
Description
The following seem to be "missing" :
strtod_l strtol_l strtoul_l wcstod_l wcstol_l wcstoul_l
Apparently they are gNUlib functions as opposed to POSIX.
NetBSD defines these (plus some additions) as
#if (_POSIX_C_SOURCE - 0) >= 200809L || defined(_NETBSD_SOURCE)
# ifndef __LOCALE_T_DECLARED
typedef struct _locale *locale_t;
# define __LOCALE_T_DECLARED
# endif
double strtod_l(const char * __restrict, char ** __restrict, locale_t);
float strtof_l(const char * __restrict, char ** __restrict, locale_t);
long double strtold_l(const char * __restrict, char ** __restrict,
locale_t);
long strtol_l(const char * __restrict, char ** __restrict, int, locale_t);
unsigned long
strtoul_l(const char * __restrict, char ** __restrict, int, locale_t);
/* LONGLONG */
long long int
strtoll_l(const char * __restrict, char ** __restrict, int, locale_t);
/* LONGLONG */
unsigned long long int
strtoull_l(const char * __restrict, char ** __restrict, int, locale_t);
...
and
#if (_POSIX_C_SOURCE - 0) >= 200809L || defined(_NETBSD_SOURCE)
# ifndef __LOCALE_T_DECLARED
typedef struct _locale *locale_t;
# define __LOCALE_T_DECLARED
# endif

These functions are not part of the POSIX specification, but are BSD additions (really inherited from Darwin I believe).
On the one hand, it seems like they would be convenient. But on the other hand, I'm moderately opposed to polluting the namespace with symbols that aren't part of standards yet -- it causes grief later if POSIX adopts a different definition.
Are there applications that actually need these symbols? Would their presence help application portability?

As these were gnulib and not POSIX, I tabled working further on the packages when I posted the issue (a placeholder for discussion).
If I come across them or any other cases again, I'll drop mention here. thx

what will be workaround for it?
will be better to see it implemented in illumos because Linux and BSD not failed with these function, but illumos does.

You may wish to try 2.0.12 (which is the version building fine in pkgsrc).
The changelog indicates patches to check for these (including one from Andy).
But since a test case came by again, I'm all for the implementation of these functions!
