Idiom #210 Compiler version and options

Assign, at runtime, the compiler version and the options the program was compiled with to variables version and options, respectively, and print them. For interpreted languages, substitute the version of the interpreter.

Example output:

GCC version 10.0.0 20190914 (experimental)
-mtune=generic -march=x86-64

use iso_fortran_env

  character(len=:), allocatable :: version, options
  version = compiler_version()
  options = compiler_options()
  print *,version
  print *,options
