OK, with the getdinfo.h patch from Mark, here's what I get:

bash-2.04$ ./tfcntl
F_SETLK/F_RDLCK:retval=0
F_GETLK:retval=33
F_SETLK/F_UNLCK:retval=0
F_GETFD:retval=0000
F_SETFL:retval=ffffffff
F_GETFL:retval=0000

I'm using Windows 98 SE with a FAT32-formatted 28GB disk (if that has any
bearing).

The demo program should include stdio.h too, to declare printf():

*** tfcntl.c.orig       Thu Nov 23 11:20:42 2000
--- tfcntl.c    Thu Nov 23 11:20:52 2000
***************
*** 1,3 ****
--- 1,4 ----
+ #include <stdio.h>
  #include <stdlib.h>
  #include <unistd.h>
  #include <fcntl.h>

Bye, Rich =]
