[boost] AIX (xlC v6.0) and Boost

Hello Boosters,

I tried searching for previous discussion of this issue, and did not locate
anything; my apologies if I missed it...

I found a problem in the boost_1_33_1 file config/compiler/vacpp.hpp for
version 6.0 of that compiler.

I was getting the classic error message from the xlC linker caused by
undefined class-level static variables:
ld: 0711-317 ERROR: Undefined symbol:
boost::details::pool::ct_lcm<8,8>::value
ld: 0711-317 ERROR: Undefined symbol:
boost::pool<boost::default_user_allocator_new_delete>::min_alloc_size

After rooting around a bit, I ended up setting the configuration switch
BOOST_NO_INCLASS_MEMBER_INITIALIZATION for v6.0.
It is already set for v5.2 and earlier versions, but it was not set for v6.0
.

In any case, enabling this switch (and thus using enums instead of
class-static variables), the compiler problems ceased.

How do I make sure this gets added to the boost config files?
