If you are using Digital's cc then do

cc -V | head -1

to get the version number of the compiler.

Our alpha reports:

DEC C V5.2-038 on Digital UNIX V4.0 (Rev. 564)
Fatal error in: /usr/ucb/what Broken pipe
Broken pipe

which basically means v5.2 of the compiler. This is significant
because people will start upgrading to v6.0 (announced recently
and should be available in January), and v6.0 supposedly
improves performance greatly.

Also, to get the correct version ("uname -a" won't report the
suffix letter, only the rev build), do :

sizer -v | cut -f1 -d';'

Our alpha reports:

Digital UNIX V4.0B  (Rev. 564)

Thanks to Andy Kahn for these tips.
