Patch to testsuite/lib/g++.exp

[Jason Merrill <jason at cygnus dot com>]

Mark, why did you put the {} in your earlier patch?

The second hunk allows a testcase to use // Special g++ Options: to
override --tool_opts, to force a particular optimization level (for instance).

2000-03-08  Jason Merrill  <jason@casey.cygnus.com>

	* lib/g++.exp (g++_init): Don't put { } around -fmessage-length=0.
	(g++_target_compile): Put test-specific options last.
