Ah, I think I've found it (foreign export), but it does not work
with ghc-4.02 (the "glibc version" from Simon Marlow - it no longer
crashes on fflush, thanks!):
[qrczak ~/haskell]$ cat M.hs
module M (call_h) where
call_h = putStrLn "Hello\n"
foreign export "call_h" call_h :: IO ()
[qrczak ~/haskell]$ ghc -c M.hs -fglasgow-exts
Name.lhs:369: Non-exhaustive patterns in function nameSortModule
[qrczak ~/haskell]$
As I can't build ghc from sources and fix the problem myself, is
there any workaround?
How is `foreign import' interface related to _ccall_? Is the first
now preferable or they both will be equally continued?
