+I know it's complicated.
+Basically there are two proglems:
+ - determining the gaps between the projs
+ - determining the biggest case constant to know the proj number for
+ the default node.
+I see several solutions:
+1. Introduce a ProjDefault node. Solves both problems.
+ This means to extend all optimizations executed during construction.
+2. Give the Cond node for switch two flavors:
+ a) there are no gaps in the projs (existing flavor)
+ b) gaps may exist, default proj is still the Proj with the largest
+ projection number. This covers also the gaps.
+3. Fix the semantic of the Cond to that of 2b)
+
+Solution 2 seems to be the best:
+Computing the gaps in the Firm representation is not too hard, i.e.,
+libFIRM can implement a routine that transforms between the two
+flavours. This is also possible for 1) but 2) does not require to
+change any existing optimization.
+Further it should be far simpler to determine the biggest constant than
+to compute all gaps.
+I don't want to choose 3) as 2a) seems to have advantages for
+dataflow analysis and 3) does not allow to convert the representation to
+2a).
