Summary: hsc2hs broken under Win32

Initial Comment:
Hi,

hsc2hs seems to be broken under Win32 with ghc 
5.04.2.  If I take a simple test program and attempt to 
compile it with hsc2hs, I get the following output:

$ make -f Makefile.ghc-win32
hsc2hs Test.hsc

If you look at the above output, you will see that it never gets 
as far as using any ".c files that are compiled seperately".  
The link errors that are reported are directly from hsc2hs 
attempting to compile, link and execute the .c file it produces 
internally (which emits a Haskell source file).

Nevertheless, it turns out that using the --ld=ghc option did 
the trick.  Thanks for pointing me in the right direction.

(GHCers:  Is there some reason to use default values of cc 
and ld that are inconsistent?)

Yes, I did. Better make sure you also use 'ghc' as your 'gcc' 
if you're compiling up any .c files separately.

Thanks for the suggestion, Sigbjorn, but did you actually try 
it?  I get exactly the same output regardless of whether or not 
I use the --cc=ghc option.

C compiler mismatch;  use hsc2hs with the option --cc=ghc 
for better results.
