Re: [ECOS] Error on Cyg_Counter::add_alarm

[Matt Jerdonek <maj1224 at yahoo dot com>]

This is a complete guess but ...

I had some problems with alarms several months ago in
the FreeBSD stack, but I can't remember the details. 
I noticed that Andrew Lunn fixed a linked list issue
in net/bsd_tcpip/current/src/ecos/timeout.c after 2.0
was released.  I updated to the tip version of the
bsd_tcpip package and got better results.

Good luck,
-- Matt
