Right, I used older headers. Sorry.

I know that there are some differences between British and American
English related to s/z. But I still doubt that comparizon is valid.
http://dict.leo.org/ende?lp=ende&p=eL4jU.&search=comparison mentions
comparison is valid for British and American (see "color comparison" entry)!

Your help page custom-predicate.html contains a link "Show output".
Clicking it I see a window with black background containing the text:

<quote>
Running 1 test case...
test.cpp(28): error in "test_list_comparizon": check compare_list

*** 1 failure detected in test suite "example"
</quote>

It seems that the text is too wide for the default font. In
Iceweasel I see

<quote>
Running 1 test case...
test.cpp(28): error in "test_list_comparizon": check compare_lists( l1, l2 ) failed. Diffe

*** 1 failure detected in test suite "example"
</quote>

Do you see the difference?

I attached a sample program in my last mail. But the problem was indeed
on my side: I tried to compile BOOST_CHECK( compare_lists<1,2>( l1, l2 ) )
but because of the comma I need to use an additional pair of commas.

Right :-)
