            Bug ID: 84500
           Summary: diagnostic says "array of chars" for arrays of
                    wchar_t, char16_t and char32_t
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: c

  Target Milestone: ---

#include <stddef.h>
#include <uchar.h>
int main() {
  wchar_t w[3] = L"abcd";
  char16_t u16[3] = u"abcd";
  char32_t u32[3] = U"abcd";
}

a.c: In function ‘main’:
a.c:4:18: warning: initializer-string for array of chars is too long
   wchar_t w[3] = L"abcd";
                  ^~~~~~~
a.c:5:21: warning: initializer-string for array of chars is too long
   char16_t u16[3] = u"abcd";
                     ^~~~~~~
a.c:6:21: warning: initializer-string for array of chars is too long
   char32_t u32[3] = U"abcd";
                     ^~~~~~~


Also:

/* { dg-options "-Wc++-compat" } */
#include <stddef.h>
int main() {
  char c[3] = "abc";
  wchar_t w[3] = L"abc";
}

a.c: In function ‘main’:
a.c:4:15: warning: initializer-string for array chars is too long for C++
[-Wc++-compat]
   char c[3] = "abc";
               ^~~~~
a.c:5:18: warning: initializer-string for array chars is too long for C++
[-Wc++-compat]
   wchar_t w[3] = L"abc";
                  ^~~~~~

Note "array chars" not "array of chars".
