Bug 22182 – importC: Error: expression expected, not `)` when casting pointer with redundant parens.

The following fails to compile: typedef struct Bar { int x; } Bar; int foo(Bar* b){ return ((Bar*)(b))->x; } int main(){ Bar b = {3}; return foo(&b); } The first relevant error is: bar.c(4): Error: expression expected, not `)` The `b` in the expression `((Bar*)(b))->x` has a redundant set of parentheses around it. Removing them it compiles fine. This pattern comes up a lot in the Python headers.

Not sure if related, but this also fails to compile: int main(){ int x = 0; return (int)(x); }
