Some minor points:

In C int can't have 8 bits. It is guaranteed to represent at least
-2^15..2^15.

Your syntax puts modifiers between the calling convention and the
external id. I agree that it's consistent. Currently ghc accepts
unsafe only between the external id and the Haskell id, and dynamic
only instead the external id.

It should not matter that C allows colons in #include. Rules of the
#include argument are implementation dependent, and it should not
be a problem if a programmer can't name a header file included into
Haskell using a colon. He will have to choose a name without a colon.

But we could also cut the last colon instead of the first: a colon
is certainly not valid in a C identifier.
