  22 /* Sometimes the behavior of a test depends upon the compiler used to
  23    compile the test program.  A test script can call get_compiler_info
  24    to figure out the compiler version and test_compiler_info to test it.
  25
  26    get_compiler_info runs the preprocessor on this file and then eval's
  27    the result.  This sets various symbols for use by test_compiler_info.
  28
  29    TODO: make compiler_info a local variable for get_compiler_info and
  30    test_compiler_info.
  31
  32    TODO: all clients should use test_compiler_info and should not
  33    use gcc_compiled, hp_cc_compiler, or hp_aCC_compiler.

  40    onto the current line and eats the newline!  That messes up TCL of
  41    course.  That happens with HP aC++ A.03.13, but it no longer happens
