I try with 3.5.9 and it works fine.
I'm surprising Samba supports fifo!

1) Compile this program available from http://www.ncad.co.jp/~komata/c-kouza12.htm

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

void main()
{
  int fd;
  char buf[256];

  if(mkfifo("FifoTest",0666)==-1){
    perror("mkfifo");
  }

  if((fd=open("FifoTest",O_WRONLY))==-1){
    perror("open");
    exit(-1);
  }

  while(1){
    fgets(buf,sizeof(buf)-1,stdin);
    if(feof(stdin)){
      break;
    }
    write(fd,buf,strlen(buf));
  }
  close(fd);
}

2) echo testtest | ./a.out

3) mount from Windows XP with "net use"

4) type FifoTest and works fine.
