embedded version number

[Brent Comsa]

Hello,
I have been 
searching the onlinedocs Index at gcc.gnu.org and I cannot seem to find a way to 
embed a "version" into an object file. 
I was looking for 
some keyword like "__DATE__" to embed a date in the object file, which we could 
then use octl dump to identify the date ("version") of the object 
file.
But using a date as 
a version number is not accurate if new objects are created repeatedly on the 
same day.
Are there any 
compiler options available to me?
