I am having a problems with doubles on an HP laptop running Windows 2000
version 5.00.2195, service pack 1.  Code and data file demonstrating the
problem is below.
This code works on other OSs and compilers.  Also included below is the
output from cygcheck -s -v -r.  I also have what I believe are related
problems
using math functions, sin() and cos(), with double arguments.  Any help
would
be appreciated.

CFLAGS= 	-c -g -Ic:/cygwin/include -ansi

================== the code =================

/* This program demonstrates a bug in cygwin under windoze 2000.

/* The same program runs just fine under Red Hat Linux 7.0 */

/* cygwin was installed directly from the web on 2/24/00 and no */
/* configuration was attempted.  It was run as configured by the */
/* web installation */

#include <stdio.h>

  FILE *fp;


  /* Read data */
  fp = fopen("test.dat", "r");
  fscanf(fp, "%d", &number);
  printf("\nNumbers");
  for (i=0; i<number; i++) {
    num_read = fscanf(fp, "%f", &y);
    if (num_read != 1) {
      printf("\nRead error!\n\n");
      exit(1);
