To regard the CVS revision of a single file in the eCos repository as an 
"eCos version" would be misleading.

The eCos library is built from a collection of eCos packages each of 
which can potentially have a different version number. Also, the same 
set of packages can be configured in many ways resulting in different 
behaviour. The presence of a version string within the eCos library 
would therefore convey little about the precise behaviour of the library.

A timestamp seems the best way to differentiate between builds.
