--- Comment #18 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Given that we already have some special handling for DECIMAL="comma", I wonder
whether one couldn't simply undo the setting by used, e.g.,
const char *decimal;
size_t decimal_len;
#if defined USE_LOCALECONV && !defined USE_NL_LANGINFO
const struct lconv *lc = localeconv ();
#endif
#ifdef USE_NL_LANGINFO
decimal = nl_langinfo (DECIMAL_POINT);
decimal_len = strlen (decimal);
assert (decimal_len > 0);
#elif defined USE_LOCALECONV
decimal = lc->decimal_point;
if (decimal == NULL || *decimal == '\0')
decimal = ".";
decimal_len = strlen (decimal);
#else
decimal = ".";
decimal_len = 1;
#endif
And then simply replace for decimal_len the existing ("." or ",") decimal
character from the read string/file by the one obtained for the local - before
sending it to strtof/strtod/strtold/strtoflt128.
(Note: decimal_len is probably nearly always == 1, but it might be different.)
