-V, -version
display compiler version and exit

-i, -info
display compiler information (build/environment) and exit

-v, -verbose
verbose mode, display additional information; multiple -v

(1) display compiler version and the commands invoked by the
compiler, (2) pass verbose option to assembler/compiler (3)
