Comment (by Herbert Valerio Riedel <hvr@…>):

 In [changeset:"13b4d0cdd18471de33ba89bda11a4b238507b7c7/integer-gmp"]:
 {{{
 #!CommitTicketReference repository="integer-gmp"
 revision="13b4d0cdd18471de33ba89bda11a4b238507b7c7"
 Drop redundant formal parameter from TAKE1_UL1_RET2

 This fixes the actual cause for #8661, i.e. a mismatch between the
 actual arity of the Cmm implementation and the arity declared in the
 foreign import statement.

 This also reverts [a3878d17/integer-gmp] as the workaround isn't needed
 anymore.
