- Update to dejagnu 1.6.3
* The internal proc 'is_remote' has been renamed to 'isremote' for
consistency with the other similar procs (eg, istarget)
* runtest now accepts --local_init and --global_init options to override
the default of reading "site.exp"
* runtest now responds consistently to all Tcl errors and generates an
UNRESOLVED result when a test script aborts
* runtest now collects Tcl errors encountered during a test run and prints
the collected errors a second time at the end of the test run after the
summary
* A utility procedure relative_filename has been added
* The utility procedure 'grep' now accepts a '-n' option that
includes line numbers in the output, consistent with GNU grep
* The target_compile procedure now accepts a "linker=" option that
overrides the compiler selection when producing an executable
* The internal default_target_compile procedure now supports compiling
sources in Go (using GCC Go) and Rust
* The host_execute procedure no longer insists that the executable be in
the current directory if the file exists under the given name
* The host_execute procedure now reads input to end-of-file
* The match patterns in the host_execute procedure have been revised to
fix timing issues causing test names to be truncated
* The host_execute procedure is no longer sensitive to the value of the
"text" global variable
* A new multiplex procedure "testsuite" is added for commands retrieving
or providing information about the current testsuite
* A command "testsuite file" is added to replace the use of the "*dir"
variables in test scripts
* A command "testsuite can call" is added to report the availability of
multiplexed API calls (forwarded request 901733 from Andreas_Schwab)
