Solution:

Compilers called from the system command line do not display graphical splash screens advertising their version number. It is therefore not always obvious which version of a given C or Fortran compiler is installed.

Below are a number of examples that can be used to determine the compiler version on a specific machine. Each platform section lists version info commands for several common compilers. The fully indented sections are example output from the command.
