Hugs version:
=============
Hugs 1.4, The Nottingham and Yale Haskell User's System. Version 970719.
Configuration options: --with-x --disable-large-banner --enable-TREX
======================
Operating System: HP-UX varsovie A.09.05 A 9000/735 2001675185 two-user license
=================
Compiler: gcc version 2.6.3
=========
Behaviour:
==========
The import declaration:
> import <path> as Id
fails if the path is relative (i.e. "utils/Foo" or "../src/Bar")
- if Hugs is exec'd via `comint' in Emacs (i.e. a hugs process is
spawned with no underlying shell);
- if runhugs is used.
Under a shell (tcsh or csh), the module is imported correctly.
Of course the solution is to use absolute file paths, with a small
sacrifice to portability.

[Transcripts follow for the curious:]
File FooA.lhs:
==============
> module Main where
> import "tmp/Foo.lhs" as Foo
> main = putStr "Hello World"
