Sorry, this isn't a "Windows feature" but 
POSIX compatible and a workaround would be 
extremly simple, because Chad Fowler made
a simple mistake: he forgotten to call 
closedir() before rmdir():

#include <stdio.h>
#include <errno.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>

/* (1) */
#include <sys/dirent.h>

int main(void)
{
 int rc;
 extern int errno;

 /* (2) */
 DIR* pDIR; 

 rc = mkdir("_blah", 0777);
 printf("mkdir %d\n", rc);

 pDIR = opendir("_blah");
 printf("opendir %d\n", ( long ) pDIR);

 /* (3) */
 rc = closedir( pDIR );
 printf("closedir %d\n", rc);

 rc = rmdir("_blah");
 printf("rmdir %d\n", rc);

 rc = mkdir("_blah", 0777);
 printf("mkdir %d\n", rc);
 printf("errno: %d\n", errno);
}

#if 0

Cygwin output:
mkdir 0
opendir 167839600
closedir 0
rmdir 0
mkdir 0
errno: 0

Linux output:
mkdir 0
opendir 134518696
rmdir 0
mkdir 0
errno: 38

#endif
