btw, in my programs (and in this lib) i explicitly unbox all the
strict fields with simple types because automatic unboxing can lead
to losed sharing of complex datastructures

it should be replaced by HsBase.h, i erroneously thinks that io.h is
available on Unix systems. HsBase.h determines itself where we can
find all definitions of these low-level functions

it should be "eof"

it should be found via HsBase.h, is not?

yes, in mingw :)
i attached updated FD.hs. but if filelength/tell cannot be found
through HsBase.h, i don't know what to do. at least,
System.Posix.Internals does the same:
foreign import ccall unsafe "HsBase.h read"
c_read :: CInt -> Ptr CChar -> CSize -> IO CSsize
foreign import ccall unsafe "HsBase.h write"
c_write :: CInt -> Ptr CChar -> CSize -> IO CSsize
it is possible that devil is in the including of those two additional
files. try to add it. otherwise, we should wait until Simon be up :)
