2290	Patch for GCC-4.0.1 compatibility (and better compile time).	Dave Abrahams	Matthias Troyer	"This patch makes the tests build on GCC-4.0.1 and leaves out what 
I believe to be the unnecessary step of checking whether a metafunction 
class is actually a placeholder expression.  If I'm understanding correcetly,
it will always be a metafunction class, and not just in the tested examples.

Note that this patch is against 1.35.x; I know things have been shuffled for 
1.36 but I assume the same transformation can be applied elsewhere.
