dot five-o series versions - GDB 6.2.50

[Andrew Cagney <cagney@gnu.org>]

Hello,

Ref: http://www.iro.umontreal.ca/translation/HTML/maintainers.html

The translators are looking for a versioning schema that makes it easy 
to undersand how two versions relate to each other.  Unfortunatly, GDB's 
current versioning doesn't do this.  Without knowing the policy, it's 
hard to know whats going on with:

	2004-09-03
	6.2_2004-09_03

consequently, I'd like to propose that things be changed to the following:

M.N.5x:
Indicate the mainline.  It's half way between releases -> .50.
Ex 6.2.50, 6.2.50_2004-09-03

M.N.9x:
Indicate pre release versions drawn from the branch.

M.N / M.N.O:
The release.

This leads to the sequence:

6.2.50_2004-09-03
6.2.50_2004-09-04
...
     <branch> -----------> <mainline>
6.2.90_2004-10-05     6.3.50_2004-10-05
