  20 /* Sometimes the behavior of a test depends upon the compiler used to
  21    compile the test program.  A test script can call get_compiler_info
  22    to figure out the compiler version and test_compiler_info to test it.
  23
  24    get_compiler_info runs the preprocessor on this file and then eval's
  25    the result.  This sets various symbols for use by test_compiler_info.

  27    TODO: make compiler_info a local variable for get_compiler_info and
  28    test_compiler_info.
  29
  30    TODO: all clients should use test_compiler_info and should not
  31    use gcc_compiled, hp_cc_compiler, or hp_aCC_compiler.
