在生成的mytest.c文件中显示信息：
/* SQLLIB Prototypes */
extern sqlcxt (/*_ void **, unsigned long *,
                   struct sqlexd *, struct sqlcxp * _*/);
extern sqlcx2t(/*_ void **, unsigned long *,
                   struct sqlexd *, struct sqlcxp * _*/);
extern sqlbuft(/*_ void **, char * _*/);
extern sqlgs2t(/*_ void **, char * _*/);
extern sqlorat(/*_ void **, unsigned long *, void * _*/);

把上述信息中定义的函数前面增加“int”再次编译可以通过，但是查看很多例子，都不需要增加“int”，不知道什么原因，请各位大侠帮忙分析。谢谢！
extern int sqlcxt (/*_ void **, unsigned long *,
                   struct sqlexd *, struct sqlcxp * _*/);
extern int sqlcx2t(/*_ void **, unsigned long *,
                   struct sqlexd *, struct sqlcxp * _*/);
extern int sqlbuft(/*_ void **, char * _*/);
extern int sqlgs2t(/*_ void **, char * _*/);
extern int sqlorat(/*_ void **, unsigned long *, void * _*/);

修改 /oracle/product/11.2.0/db_1/precomp/admin的 pcscfg.cfg文件
CODE=ANSI_C
再次编译程序，原先的警告信息没有，最终成功完成，生产exe可执行程序。呵呵

omission of explicit type is nonstandard ("int" assumed)
洋文的意思是
extern sqlcxt (……);
要写上返回类型。在古老的C标准中不写那么默认返回int类型，但现代的C标准要求必须写明
