OK, the preprocessor problems now are gone.

Yes, it's a non-Windows system.

Now I have the following issues:

1) I need to increase the maximum number of pending instantiations, it 
seems that the default value of the compiler (64) is not enough. This is 
also true for the acc toolset, AFAICT.

2) I get a number of compile time errors along the lines of:

cxx: Error: integer_test.cpp, line 623: expression must have a constant value
           (exprnotconst)
     BOOST_CHECK_EQUAL( static_cast<typename
----^
cxx: Error: ../../../boost/integer.hpp, line 375: class 
"boost::maximum_unsigned_integral<<error-constant>>" has no member "type"
           (notmember)
           detected during instantiation of class 
"boost::uint_value_t<Value> [with Value=<error-constant>]" at line 623 of 
"integer_test.cpp"
       typedef typename maximum_unsigned_integral<Value>::type  least;
---------------------------------------------------------^

It looks like all EDG based compilers are flagging this error, see for 
example http://tinyurl.com/58s3zc.

3) There are quite a few warning about truncation of values or sign 
changes, where I can't tell whether they are expected or not.
