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
