Ralph,

Ick - usually tools support some kind of version option. :-(

In the olden days, -V (big V) was a reasonably standard request for version no. (little V being verbosity).  The GHNU command line parsing added the wordy options preceded by double dashes.  Unfortunately, gcc does not follow this convention (aargh).

savaii:~ baker$ gcc -V
gcc-4.2: argument to `-V' is missing
