--- All the static flags should appear in this list. It describes how each
--- static flag should be processed. Two main purposes:
--- (a) if a command-line flag doesn't appear in the list, GHC can complain
--- (b) a command-line flag may remove, or add, other flags; e.g. the "-fno-X" things
---
--- The common (PassFlag addOpt) action puts the static flag into the bunch of
--- things that are searched up by the top-level definitions like
--- opt_foo = lookUp FSLIT("-dfoo")
-
--- Note that ordering is important in the following list: any flag which
--- is a prefix flag (i.e. HasArg, Prefix, OptPrefix, AnySuffix) will override
--- flags further down the list with the same prefix.
