+Subject: [PATCH] Fix precedence of casts
+
+Casts should have the same high precedence as unary plus and minus, but
+actually had a lower precedence than anything else.
+
+This could lead to the wrong type being deduced in obscure cases, but
+also prevented SWIG deducing a type for expressions such as (0)*1+2
+which SWIG parses as a cast and then fixes up afterwards.
+
+A bug fixed in 4.3.0 made this latter problem manifest more often
+(previously type deduction happened to work for (0)*1+2 due to an
+internal field not getting cleared properly).
+
+Fixes #3058
