commit cf85e7034ad5640b18a3b68d6b291b7bf89bfc80 Author: Jose Luis Duran <[email protected]> AuthorDate: 2025-11-26 20:34:56 +0000 Commit: Jose Luis Duran <[email protected]> CommitDate: 2025-11-26 20:34:56 +0000 strfmon: Fix negative sign handling for C locale If the locale's positive_sign and negative_sign values would both be returned by localeconv() as empty strings, strfmon() shall behave as if the negative_sign value was the string "-". This occurs with the C locale. The implementation previously assigned "0" to sign_posn (parentheses around the entire string); now it assigns it to "1" (sign before the string) when it is undefined (CHAR_MAX). Austin Group Defect 1199[1] is applied, changing the requirements for the '+' and '(' flags.
