编译的问题

Guys,
In Fluent, I compiled my UDF. The system gave the information: =========================
\fluent.inc\fluent6.3.26\src\machine.h(114) : warning C4005: ';stdout'; : macro redefinition
\Program Files\Microsoft Visual Studio 8\VC\INCLUDE\stdio.h(160) : see previous definition of ';stdout';

Creating library libudf.lib and object libudf.exp
Done. ==================================================
在UDF中, 我想把计算结果用"printf"显示在出来。但是这个命令不能被执行。大家帮忙看看，问题是不是与这些警告有关？如何解决？谢谢！Braket
