Cygwin

This is: Win2K advanced server, SP4+all updates, cygwin w most (but no all)
recent updates and the 2004-04-20 snapshot dll.

$ cat stat.c
#include <string.h>
#include <stdio.h>
#include <sys/stat.h>

int main()
{
    char filename[1024];
    struct stat sb;

    strcpy(filename, "a");
    while(strlen(filename) < 1023)
    {
        strcat(filename, "a");
        printf("filename length %d\n", strlen(filename));

#ifdef DOSTAT
        stat(filename, &sb);
#endif

    }
    return 0;
}
$ gcc -DDOSTAT -o stat stat.c && stat >stat-run
$ gcc -o stat stat.c && stat >stat-chk
$ diff -u0 stat-*
$ ls -l stat-*
-rw-r--r--    1 Hannu       20358 May  5 21:36 stat-chk

Looks to me like you might have a fix in trying some of the snapshot dll's.
Test run on 8GB FAT32 and NTFS partitions, no diff.
