Comment:
I've done the `--print-foo` part of this ticket.
The gcc situation is rather complex. We have
{{{
pgm_c :: (String,[Option])
opt_c :: [String]
}}}
and we also do this when running gcc:
{{{
-- If the -B<dir> option is set, add <dir> to PATH. This works around
-- a bug in gcc on Windows Vista where it can't find its auxiliary
-- binaries (see bug #1110).
getGccEnv :: [Option] -> IO (Maybe [(String,String)])
getGccEnv opts =
if null b_dirs
then return Nothing
else do env <- getEnvironment
return (Just (map mangle_path env))
where
(b_dirs, _) = partitionWith get_b_opt opts
get_b_opt (Option ('-':'B':dir)) = Left dir
get_b_opt other = Right other
mangle_path (path,paths) | map toUpper path == "PATH"
= (path, '\"' : head b_dirs ++ "\";" ++ paths)
mangle_path other = other
}}}
Likewise for cpp, as and ld. What exactly does Cabal want to know?
