请教编译天网TSE时的错误信息

编译时出现的错误信息：

uri.l: In function ‘urilex’:
uri.l:494: error: lvalue required as increment operand
uri.l:494: error: lvalue required as increment operand
uri.l:494: error: lvalue required as increment operand

uri.l:850: error: lvalue required as increment operand


平台是REDHAT5.4

代码如下：
C/C++ code

curpos = reg_name;
        if (__uri->authority)
        {
            if (__uri->authority->userinfo)
            {
                MEMCPY_PLUS(curpos, __uri->authority->userinfo,     //494行
                            strlen(__uri->authority->userinfo));
                *curpos++ = '@';
            }

            if (__uri->authority->host)
                MEMCPY_PLUS(curpos, __uri->authority->host,        //500行
                            strlen(__uri->authority->host));

            if (__uri->authority->port)
            {
                *curpos++ = ':';
                MEMCPY_PLUS(curpos, __uri->authority->port,
                            strlen(__uri->authority->port));
            }

请问有没有人弄过？谢谢。
