After much lamenting this morning, I have come up with what I feel comfortable
as a "working" DAHDI patch set. This is useful if you are wanting to "roll your own"
app_rpt system (perhaps on some non-(Centos 5.X 32 bit) platform).

If you take any of the distros of DAHDI 2.5.1 or newer, and apply these patches,
it should "work".

This patch set may be obtained from:

https://allstarlink.org/fixed-dahdi-patches.tar.gz

or from SVN at:
