Ok. Then, comeau.hpp should define BOOST_MSVC when in MSVC mode, since it
acts exactly like it, right?

I noticed that about 15 of them are wrappers against #pragma once, I reckong
those could be replaced with almost no harm.
About the _MSC_VER tests in arithmetic_traits.hpp, I've noticed that there
are two macros exactly about int64 support: namely, BOOST_NO_INT64_T and
BOOST_NO_INTEGRAL_64_T. So, the code in the file should be modified to check
the presence of this macro, rather than doing a test for the presence of a
certain compiler (since cstdint.hpp already contains all the logic to handle
64bit types). Four lines above, it tests for BOOST_HAS_LONG_LONG before
using 'long long' so I guess it should be the same for int64. Am I right?
Also, cstdint.hpp, which defines the above macros, does not take into
account Comeau at all. As already specified, Comeau supports __int64 in MSVC
mode (_MSC_VER > 1), while it doesn't support it in strict mode (_MSC_VER ==
1). It looks to me that the test should be added around line 231:
# elif (defined(BOOST_MSVC) && (BOOST_MSVC >= 1100)) ||
(defined(__BORLANDC__) && (__BORLANDC__ >= 0x520))
// we have Borland/Microsoft __int64:
