21/* Sometimes the behavior of a test depends upon the compiler used to
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.
27
28   TODO: make compiler_info a local variable for get_compiler_info and
29   test_compiler_info.
30
31   TODO: all clients should use test_compiler_info and should not
32   use gcc_compiled, hp_cc_compiler, or hp_aCC_compiler.

37   hp c++ have a bug in string preprocessing: if the last token on a
38   line is a string, then the preprocessor concatenates the next line
39   onto the current line and eats the newline!  That messes up TCL of
40   course.  That happens with HP aC++ A.03.13, but it no longer happens
41   with HP aC++ A.03.45. */
