It would be interesting to
know the reasons for the failures however and what is different about the
x86-64 environment that resulted in test differences that ended up being
classified as failures.

 I don't know specifically, but with my very limited experience with C++, the
X86_64 compiler is much less accepting of the syntax that the Alpha and IA64 compilers
accepted.
 Some of the changes are pretty mechanical (casting or simple refactoring); some are not.
 Don't ask me to describe the "some are not" part, because I'm getting help to deal wit
those.

Being more strict is just one thing.
I also believe it is missing some of the VMS specific extensions.
And it has different size of long and pointers. Causing problems
for two cases:
* code that make implicit assumptions that those are 32 bit
* mixing C and C++
