  22    compile the test program.  A test script can call get_compiler_info
  23    to figure out the compiler version and test_compiler_info to test it.
  24
  25    get_compiler_info runs the preprocessor on this file and then eval's
  26    the result.  This sets various symbols for use by test_compiler_info.

  29    test_compiler_info.

  32    use gcc_compiled, hp_cc_compiler, or hp_aCC_compiler.
