pro c compiler and POSIX_SOURCE

Hi,
I am using Oracle 7.3.1 .
On some versions of Unix (e.g TRU64). I get strange syntax errors in header files with the
PRO-C compiler.

E.G
test.h  

typedef struct {
pid_t pid;
}
produces the a syntax error on line pid_t pid; pid_t is defined in a system header file.

What I cannot understand if in test.c
#include <test.h>
#define _POSIX_SOURCE

if I comment out the #define _POSIX_SOURCE line. All syntax errors in header file disappear.

Any ideas,
