usleep exists on Win32 as the Sleep command (it takes a millisecond value as parameter) so here is the patch for making the usleep() php function to work on win32 platforms:

in main/win95nt.h, line 27:

#define php_sleep(t)	Sleep(t*1000)

add the following line so it looks like:
#define php_sleep(t)	Sleep(t*1000)
#define usleep(t)  Sleep(t)

and in config.w32.h, line 93:

/* Define if you have the usleep function.  */
#undef HAVE_USLEEP

change it to:

/* Define if you have the usleep function.  */
#define HAVE_USLEEP 1

oops... my previous patch was incorrect, let me start over:

in main/config.w32.h, line 93:

/* Define if you have the usleep function.  */
#undef HAVE_USLEEP

change it to:

/* Define if you have the usleep function.  */
#define HAVE_USLEEP 1

in win32/time.c, line 53:

void usleep(unsigned int useconds)
{
	__int64 mstimer, freq;
	long now, then;
	if (QueryPerformanceFrequency((LARGE_INTEGER *) & freq)) {
		QueryPerformanceCounter((LARGE_INTEGER *) & mstimer);
		now = (long) (((__int64) (mstimer * .8)) % 0x0FFFFFFF);
		then = now + useconds;
		while (now < then) {
			QueryPerformanceCounter((LARGE_INTEGER *) & mstimer);
			now = (long) (((__int64) (mstimer * .8)) % 0x0FFFFFFF);
		}
	} else {
		/*workaround for systems without performance counter
		   this is actualy a millisecond sleep */
		Sleep((int) (useconds / 1000));
	}
}

change it to:

void usleep(unsigned int useconds)
{
#if 0
	__int64 mstimer, freq;
	long now, then;
	if (QueryPerformanceFrequency((LARGE_INTEGER *) & freq)) {
		QueryPerformanceCounter((LARGE_INTEGER *) & mstimer);
		now = (long) (((__int64) (mstimer * .8)) % 0x0FFFFFFF);
		then = now + useconds;
		while (now < then) {
			QueryPerformanceCounter((LARGE_INTEGER *) & mstimer);
			now = (long) (((__int64) (mstimer * .8)) % 0x0FFFFFFF);
		}
	} else {
		/*workaround for systems without performance counter
		   this is actualy a millisecond sleep */
		Sleep((int) (useconds / 1000));
	}
#else
  Sleep((DWORD) useconds);
#endif
}

and now it works great :)
can someone reflect this patch in the cvs tree?
