embedded version number

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?
 
Bc

That's because the GCC documentation often doesn't document features
that are supposed to be part of any C compiler.  The ISO C Standard
specifies __DATE__ and __TIME__.  Both, taken together, should
probably be enough for what you need.  If not, you may try
-D__PROCNUM__=$$ :-)
