Comment:

 OK I've done this, as above
 {{{
 Thu Jan  7 07:10:02 PST 2010  simonpj at microsoft.com
   * Clarify error message (Trac #3805)

     M ./compiler/parser/RdrHsSyn.lhs -1 +1
 }}}
 and
 {{{
 Tue Jan  5 09:55:32 GMT 2010  simonpj at microsoft.com
   * Improve error message (idea in Trac #3805)

   If we see

      foreign export ccall foo :: ...blah...

   we now use the "foreign" to suggest -XForeignFunctionInterface

     M ./compiler/parser/RdrHsSyn.lhs -1 +13
 }}}
