            Bug ID: 83592
           Summary: [8 Regression] Annoying -Wparentheses warnings
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trippels at gcc dot gnu.org
                CC: nathan at gcc dot gnu.org
  Target Milestone: ---

Building anything QT related gives many annoying -Wparentheses warnings, e.g.:

 % cat test.ii
int* foo(long &a) { return reinterpret_cast<int(*)>(&a); }

 % g++ -Wall -c test.ii
test.ii: In function ‘int* foo(long int&)’:
test.ii:1:48: warning: unnecessary parentheses in declaration of ‘type name’
[-Wparentheses]
 int* foo(long &a) { return reinterpret_cast<int(*)>(&a); }
                                                ^
I don't see what harm these parentheses could cause in this context.
