+*** Some random stuff for testing libU77. Should be done better. It's
+* hard to test things where you can't guarantee the result. Have a
+* good squint at what it prints, though detected errors will cause
+* starred messages.
+*
+* Currently not tested:
+* ALARM
+* CHDIR (func)
+* CHMOD (func)
+* FGET (func/subr)
+* FGETC (func)
+* FPUT (func/subr)
+* FPUTC (func)
+* FSTAT (subr)
+* GETCWD (subr)
+* HOSTNM (subr)
+* IRAND
+* KILL
+* LINK (func)
+* LSTAT (subr)
+* RENAME (func/subr)
+* SIGNAL (subr)
+* SRAND
+* STAT (subr)
+* SYMLNK (func/subr)
+* UMASK (func)
+* UNLINK (func)
+*
+* NOTE! This is the libU77 version, so it should be a bit more
+* "interactive" than the testsuite version, which is in
+* gcc/testsuite/g77.f-torture/execute/u77-test.f.
+* This version purposely exits with a "failure" status, to test
+* returning of non-zero status, and it doesn't call the ABORT
+* intrinsic (it substitutes an EXTERNAL stub, so the code can be
+* kept nearly the same in both copies). Also, it goes ahead and
+* tests the HOSTNM intrinsic. Please keep the other copy up-to-date when
+* you modify this one.
