As of X11R6.3, imake parses the output of 'uname -r' to automatically
set the OSMajorVersion, OSMinorVersion and OSTeenyVersion parameters.
I recently updated a box with 2.1.7.1 to the latest on the RELENG_2_1_0
branch, and as a consequence, 'uname -r' now reports "2.1-STABLE" rather
than "2.1.7.1-RELEASE".  This results in imake setting OSTeenyVersion
to 0 rather than 7, and this does make a difference with the current
FreeBSD.cf.

Is there a better way to reliably distinguish between versions,
particularly the vintage of one of the "-STABLE" versions?  The imake
config allows these version parameters to be manually overriden, and
that's what I'm doing for now.  It would be good if the auto-detect
mechanism could be made to work in this case though.  I don't mind so
much about -CURRENT, since that's known to be more of a moving target.
