Bug#848899: Report is unclear

[Julien Puydt]

Hi,

I don't understand why the bug reports ends with a discussion of the 
count_trailing_zeros and count_leading_zeros macros, since the error 
message quoted seems to be about the UWtype typedef.

Notice that I won't have time to have a look before next week (at 
least), so if you find a worthy solution, don't hesitate to team-upload 
a new version!
