Hmm.  Before I read this mail, I think you change only non-generated source
files. So If I write better Setup.(l)hs file or, add H/Direct's ihc and  
apply different
option file by file support, I can made newer cabalised version HDirect  
package -
just replace source files.

Anyway, I think that ihc - an IDL compiler for Haskell - support for Cabal  
is useful.
So I send mail, this time.

I already made initial that ... but if make buildable Haskell source file,  
I have to
use different option one by one, like this;

= lib/Makefile =
WideString_IHC_OPTS  += -fno-imports -fno-export-lists -fkeep-hresult  
-fout-pointers-are-not-refs
PointerPrim_IHC_OPTS += -fkeep-hresult -fout-pointers-are-not-refs

= comlib/Makefile =
AutoPrim_IHC_OPTS    += -fno-imports -fno-export-lists -fhs-to-c   
-fno-overload-variant -fout-pointers-are-not-refs  
-fsubtyped-interface-pointers
ComPrim_IHC_OPTS     += -fno-imports -fno-export-lists  
-fout-pointers-are-not-refs
WideString_IHC_OPTS  += -fno-imports -fno-export-lists -fkeep-hresult  
-fout-pointers-are-not-refs
PointerPrim_IHC_OPTS += -fkeep-hresult -fout-pointers-are-not-refs
StdTypes_IHC_OPTS    += -fno-export-list -fno-gen-variant-instances  
-fout-pointers-are-not-refs --gen-headers
SafeArray_IHC_OPTS   += -fhs-to-c -fno-export-lists --gen-headers  
-fout-pointers-are-not-refs --gen-headers
TypeLib_IHC_OPTS     += -fno-export-list -fappend-interface-short-name  
-fno-overload-variant --gen-headers
Connection_IHC_OPTS  += -fappend-interface-short-name

and I didn't support this feature yet.

If you use atttached hdirect.cabal file, after applied  
cabal-ihc-support.patch for darcs
repository, you can see compile error from generated file.

Does anyone have good idea?
