Strange error of gcc.

Hello,
When I try to compile a program with GCC a error like this is printed:

> error: two or more data types in declaration of `IP'
> error: duplicate `typedef'

if I erase this declaration another declaration is a error:

> /usr/lib/gcc/i386-redhat-linux/3.4.3/include/stddef.h:213: error: two or more data types in declaration of `size_t'
> /usr/lib/gcc/i386-redhat-linux/3.4.3/include/stddef.h:213: error: duplicate `typedef'

I can not locate the cause of error, anyone known how to locate the error? Any option of GCC to trace it?

Thanks in advance.
