Comment(by dterei):
OK also from GMP Docs:
{{{
Counts of bits of a multi-precision number are represented in the C type
mp_bitcnt_t. Currently this is always an unsigned long, but on some
systems it will be an unsigned long long in the future.
}}}
So I guess we should apply two casts. The other option is to add code to
the LLVM backend to handle doing implicit coercions making it compatible
with NCG as bugs of this nature come up every few months. However I'd like
to avoid that as its only the hand written cmm code that it can occur in
so for now dealing with these on a case by case basis seems OK.
