在生成的mytest.c文件中顯示信息：
/* 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 * _*/);

把上述信息中定義的函數(shù)前面增加“int”再次編譯可以通過(guò)，但是查看很多例子，都不需要增加“int”，不知道什么原因，請(qǐng)各位大俠幫忙分析。謝謝！
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
再次編譯程序，原先的警告信息沒(méi)有，最終成功完成，生產(chǎn)exe可執(zhí)行程序。呵呵

omission of explicit type is nonstandard ("int" assumed)
洋文的意思是
extern sqlcxt (……);
要寫上返回類型。在古老的C標(biāo)準(zhǔn)中不寫那么默認(rèn)返回int類型，但現(xiàn)代的C標(biāo)準(zhǔn)要求必須寫明
