I believe this is related to a recent glibc change (allowing 128 bit floats). This same issue can be had trying to compile anything with nvcc - the compiler throws a similar error. Either this blocks new glibc or this package needs to be patched to support 128 bit floats (or you can hack that header).

(In reply to Adam Stylinski from comment #8) > see also: > > https://github.com/haskell/c2hs/issues/192 > https://github.com/visq/language-c/pull/41 Right you are! I'll try to pull new c2hs from ::haskell into ::gentoo.
