*** 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.
