Sorry for jumping into another bug but I think it is for good reason.

Talking about "description" there is one issue for which I planned to ask for
help but I forgot. It affects:
http://bugs.ecos.sourceware.org/attachment.cgi?id=1079 and
http://bugs.ecos.sourceware.org/attachment.cgi?id=1080

Descriptions for interrupt priority look like this:
description "
            This option selects the interrupt priority for the EMAC interrupts. 
            There are CYGNUM_DEVS_ETH_IRQ_PRIORITY_LEVELS priority levels
            corresponding to the values 0 through 
            CYGNUM_DEVS_ETH_IRQ_PRIORITY_LEVELS-1 decimal, of which the highest
            value is the lowest priority. The reset value of 
            these registers defaults all interrupts to the lowest priority, 
            allowing a single write to elevate the priority of an 
            individual interrupt."

I know that this is less than perfect, but with my limited knowledge of tcl/CDL
I failed to find a way to enforce substitution of
CYGNUM_DEVS_ETH_IRQ_PRIORITY_LEVELS. I tried something like
      "xxx" . CYGNUM_DEVS_ETH_IRQ_PRIORITY_LEVELS . "xxx"
and some other combinations involving braces and brackets.
Hope there is a way to do it.
