I have set the FILES variable using "Properties", selecting the 
"Advanced" tab and clicking
the "Environment Variables" button. In the system or administrator part, 
I have added the
FILES system variable.

I have installed WinXP home edition SP2 on my computer two weeks ago so 
Iam still not familiar
with it. Maybe I have brocken something during the installation. As 
suggested, I have written a
small test program that tries to open as much as possible files. I have 
compiled the program with
the tools from beta/v2gnu and a fresh compiled cvs djgpp (2005-01-25) 
from www.ludd.luth.se/~ams.
It opens 17 files starting with handle 5 and it stops with: Permision 
denied (EACCES).

If I run the same program using gdb then it starts with handle 10 and 14 
files
are opened and it stops with:  Too many open files (EMFILE).

If I run the same program on Win98SE, after having recompiled it with 
the djdev203
tools,  then the first handle is 6 and 32 files are opened. The program 
stops
with: Too many open files (EMFILE). On Win98SE I have not set the FILES 
variable
 in config.sys.
