Sorry if i'm posting too much, it's my last post for this ...

int
base64_decode_max_arg_length()
{
#if (SIZEOF_INT == 8)
  return 0x7FFFFFFFFFFFFFFFLL;
#else
  return 0x7FFFFFFF;
#endif
}

if we reeturn LL (longlong) with a int function, this will cause overflow/warnings at gcc? will the long long be returned with the right value?

int
main(void)
{

base64.c is a binary program too? could we compile it as mariadb_base64 ? this help debuging something like ENABLE-BASE64-BINARY, or some README file showing how to do this

well :) that's all :) at weekend i report if i found something strange or bugs :)

bye
