Works fine in Cygwin, I just tested it:

  # cat > chdir.c << EOF
  #include <stdio.h>
  #include <limits.h>

  int
  main (int argc, char **argv)
  {
    int ret = 0;
    if (argc > 1)
      ret = chdir (argv[1]);
    if (ret)
      perror ("chdir");
    else
      {
	char buf[PATH_MAX];
	getcwd (buf, PATH_MAX);
	printf ("pwd: %s\n", buf);
      }
    return ret ? 1 : 0;
  }
  EOF
  $ gcc -g -o chdir chdir.c
  $ ./chdir C:/Windows
  pwd: /cygdrive/c/Windows

It's a problem in dash apparently.  Btw., tcsh also has a problem
with DOS paths, if you use backslashes, see the prompt:

  [~]$ cd C:\\Windows
  [~/C:\Windows]$ pwd
  /cygdrive/c/Windows

I just don't care enough for DOS paths so I won't fix.
