Alpine 3.23 ships with GCC 15, which uses C23 as the default language standard. In C23, empty parentheses `()` in function declarations mean "no arguments" (like C++) instead of "unspecified arguments" (C17 and earlier). Several dependencies (MIT Kerberos 1.21.3, Cyrus SASL 2.1.28) use old-style K&R declarations that conflict with proper prototypes, causing build errors like: error: conflicting types for 'ss_delete_info_dir'; have 'void(void)' error: too many arguments to function 'MD5_memcpy'; expected 0 This fix adds -std=gnu17 globally in setup_musl_compiler() to force C17 semantics for all dependency builds. This is fully backwards compatible since GCC 8-14 already used gnu17 as the default.
