            Bug ID: 109021
           Summary: accept size parameter in extern C
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: muecker at gwdg dot de
  Target Milestone: ---

A problem I encounter sometimes when using newer C headers in C++ is
with functions that have array argument with a size parameter:

extern "C" void foo(int N, char buf[N]);

I think g++ should accept this in general or only for extern "C".

At least for 1D arrays this should be easy as it could simply ignore the si=
ze=20
and only emit a diagnostic with -pedantic.=
