[Message part 1 (text/plain, inline)]

Hi,

thanks for the patch!  I applied it, tried it, and ran into some build
issues.  Maybe I missed something; here is (roughly) what I tried:

Ignorant of the patch provided here, I tried to build newer versions of
ghc-attoparsec / its dependants and ended up with the attached patch.
Using this patch, the build succeeds (but I am not sure if the patch's
approach is sensible).
