Please don't try to use a 3.14 support in a 3.13 application.
It is not supported.

For 3.14.3 the old config as well as the configure rules are still supported but 
the old config rules only work for vxWorks IOCs.

Starting with 3.15, and perhaps sooner, the old config rules will no longer be 
supported.

One of my tests for 3.14 is for a test stand that has many of the VME devices 
supported in the 3.13 releases. I unbundled the hardware support from base and 
until recently I built the support with the old config rules. This made the 
application more difficult to understand because it was a strange combination of 
old and new rules. Starting with 3.14.3 I am building all the hardware support 
using the latest 3.14.3 build rules.

I am responsible for the allenBradley 6008 scanner based support. I must support 
it on both 3.13 and 3.14. In the CVS repository I created a branch for the 3.13 
version and maintain the 3.14 version on the main branch. This is easier than 
trying to maintain the 3.13 and 3.14 versions in the same tree like I did 
previously.

Bottom line. Don't build with a combination of 3.13 and 3.15 components. It will 
cause more problems then it solves.
