My guess (a complete guess) is that the deliterate step is creating a
temporary .hs file elsewhere on your filesystem, which is why the CPP
step can't find B.hs without a fully-qualified path.
That is what is happening (you can confirm with "ghc -v").

Interestingly, you can work around by compiling with -I. on the command line:

{{{

mbolingbroke@equinox ~/Junk/lhscpp
$ cat Test.lhs Included.h
...
{-# LANGUAGE CPP #-}
module Main (main) where
#include "MachDeps.h"
#include "Included.h"
...
main :: IO ()
main = print MY_CONSTANT
#define MY_CONSTANT 2
mbolingbroke@equinox ~/Junk/lhscpp
$ ./Test
2
}}}
Perhaps worth filing a bug report?
