An example from libhugetlbfs. Note the original call wasn't recursive,
following is reduced code I got from delta.

$ cat gethugepagesizes.c 
extern __inline __attribute__ ((__always_inline__))
     int open (__const char *__path, int __oflag, ...)
{
}

void cleanup (void);
open (const char *file, int flags, ...)
{
  char fname[4096 + 1];
  int fd;
  cleanup ();
  fd = open (fname, 01 | 0100);
}

void cleanup (void)
{
  cleanup_fake_data ();
}
$ ~/install/gcc/trunk/bin/gcc -O3 -c gethugepagesizes.c
