import PrelAddr

[Rafael Martinez Torres]

I'm rewriting some old code,originally written for ghc-4.08.2 .

1)Now, when I compile with ghc-5.02 , fails:

ghc -cpp -fglasgow-exts -O -fvia-C -syslib lang -syslib concurrent -c
foo.hs

foo.hs:47:
    failed to load interface for `PrelAddr':
	Could not find interface file for `PrelAddr'
gmake: *** [foo.o] Error 1


2)if commented,
--import PerlAddr

ghc -cpp -fglasgow-exts -O -fvia-C -syslib lang -syslib concurrent -c
foo.hs

foo.hs:112: Type constructor or class not in scope: `Addr'

foo.hs:514: Data constructor not in scope: `A#'

gmake: *** [foo.o] Error 1


3)In doc available I'm recommended to import Foreign

import Foreign

ghc -cpp -fglasgow-exts -O -fvia-C -syslib lang -syslib concurrent -c
foo.hs

foo.hs:511: Data constructor not in scope: `A#'

gmake: *** [foo.o] Error 1



What should I import to use unboxed types and constructors ? You see the
"-fglasgow-exts" .
