 This survived an x86-linux bootstrap and reports the following test
 suite failures.  I do not know if they are regressions or not.
 
 FAIL: g++.dg/vtgc1.C scan-assembler (about 30 of these)
 FAIL: g++.ext/instantiate1.C not instantiated (test for errors, line 18)
 FAIL: g++.ext/instantiate1.C not instantiated (test for errors, line 20)
 FAIL: g++.jason/2371.C (test for excess errors)
 FAIL: g++.other/crash32.C (test for excess errors)
 FAIL: g++.other/loop2.C caused compiler crash

 State-Changed-Why:
     This is the well-known parser error in G++, that can only be fixed with a parser rewrite.  I don't think it's worth keeping this bug report open; we all know about the problem.
