            Bug ID: 89264
           Summary: Incorrect bitfield type in -Wconversion warnings
           Product: gcc
           Version: 7.4.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pskocik at gmail dot com
  Target Milestone: ---

void f() { struct{ unsigned x:1; }x = { (unsigned){0} }; }

warns about a conversion to `unsigned char:1`. It should say `unsigned int:1`.
