我正在尝试编译一个非常旧的PHP版本，并遇到此错误：
/tmp/php-5.0.5/ext/openssl/openssl.c:3198:11: error: expected ';' before '__s1_len'
/tmp/php-5.0.5/ext/openssl/openssl.c:3198:11: error: '__s1_len' undeclared (first use in this function)

第3198行：
match = strcmp(cnmatch, buf) == 0;
那条线对我来说很好吗？我也没有在文件中的任何地方看到__s1_len。不在3198行或与此相关的任何其他行上。
有什么想法吗？
