On alpha-redhat-linux, the only failing test was:
./bitfield3
Test 4 Failure: bitfield3.cpp:60
This is about:
struct A { char a; char b:1; int :0; char c:1; char d; };
sizeof(A). g++ 3.2 gives 6, the testsuite expects 2*sizeof(int).
That's the same result as given on IA-32 or IA-64, but those
tests are
#if !defined __i386__ && !defined __ia64__
Guess at least __alpha__ is a good candidate for this treatment too.
On ia64-redhat-linux, all tests passed.
Bootstrapping sparc-redhat-linux and sparc64-redhat-linux now and
will run the testsuite there too.
