#3742: redundant space in FFI imports rejected by 6.12

Component: Compiler (Parser) | Version: 6.12.1 RC1
Keywords: | Difficulty:

Architecture: Unknown/Multiple | Failure: GHC rejects valid program
----------------------------------+-----------------------------------------
GHC 6.10 and older accepted this code:
{{{
foreign import ccall unsafe " g_get_application_name"
g_get_application_name :: (IO (Ptr CChar))
}}}
GHC 6.12 now rejects it with
{{{
glib/System/Glib/Utils.chs:81:28: Malformed entity string
}}}
The problem is the leading space in the C entity string. This code is
generated by c2hs which is doing `header ++ " " ++ ident` however the
header may be empty.
We should probably allow this code, though possibly with a warning. In
parallel, c2hs could be fixed so it doesn't do that.
