patch applied (c2hs): Allow various GNU C builtins that take types as parameters

They are entered into the AST with only a place holder, not the full info. M ./c2hs/c/CAST.hs -1 +4 M ./c2hs/c/CLexer.x +5 M ./c2hs/c/CParser.y +22 M ./c2hs/c/CTokens.hs +6

patch applied (c2hs): GNU C allows comitting the middle expr in conditional expressions
by Duncan Coutts 25 Mar '07

25 Mar '07

Sun Mar 25 05:50:51 PDT 2007 Duncan Coutts <duncan.coutts(a)worc.ox.ac.uk> * GNU C allows comitting the middle expr in conditional expressions so normally it's: <condition-exp> ? <then-exp> : <else-exp> and GNU allows: <condition-exp> ? : <else-exp> which in the 'then' case evaluates to <condition-exp>. The advantage here is that the condition exp is evaluated only once. M ./c2hs/c/CAST.hs -1 +1 M ./c2hs/c/CNames.hs -1 +1 M ./c2hs/c/CParser.y -1 +7
