[C2hs] patch applied (c2hs): Add shadowTypedef operation to parser monad

Mon Feb 19 12:35:13 PST 2007 Duncan Coutts * Add shadowTypedef operation to parser monad Local vars in inner scopes can shadow type names so we need to be able to adjust the current typedef identifier set accordingly (ie delete identifiers from the typedef ident set). For example: typedef int X; /* X declared as a type name */ void foo() { int X; X = X +1 } /* X redeclared as a local var */ M ./c2hs/c/CParserMonad.hs -1 +11
