Nope.
I talk about all those 
WE_SUPPORT_EVEN_THE_STUPIDEST_MSVC()
and
GCC_HAS_A_BUG_BUT(WE_KNOW_HOW_TO_DEAL_WITH_IT)

OTOH I must admit that I was yet just too unmotivated to 
figure out all those workarounds, since I hvae Intel's C++
which does not complain about the products of my wicked mind. 

My own lib, Daixtrose, simply ignores compilers
that do not fit (unfortunately even gcc now fails).
C++ is much more fun this way.

I _should_ indeed take the time to make it more portable,
this is why I am interested in tricks like

BOOST_MPL_AUX_VOID_SPEC_PARAM(C)
BOOST_MPL_AUX_VALUE_WKND(C)::value
BOOST_MPL_AUX_LAMBDA_SUPPORT

OTOH do not hesitate to write a book about
the prepro lib. It's so powerful and I have it in mind
for future usage.
I offer proofreading without fees ...

Best regards,

Markus
