Unfortunately, I was not able to compile the type_with_alignment with my
Builder 5.0 update patch 1.
There are a few problems that I solved with a small refactoring (In
particular,  it fails to recognize foo<typename fred::bar> unless you remove
the typename keyword), but at the end it just got stuck at a : F1004
Internal compiler error at 0x12a5319 with base 0x1200000

The same happened trying to use boost::mpl to perform the search in the type
list.

Anyway, I got the idea so I'll keep trying to find a syntax that the Builder
compiler can manage.

Thank you.
