            Bug ID: 31412
           Summary: GCC 6 failed to build i386 glibc on Fedora 39
           Product: glibc
           Version: 2.40
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build

  Target Milestone: ---
            Target: i386

[hjl@gnu-cfl-3 tmp]$ cat x.c
#include <iostream>

int
main ()
{
  std::cout << "Hello, world!";
  return 0;
}
[hjl@gnu-cfl-3 tmp]$ /usr/gcc-6.4.1-x32/bin/g++ -m32 x.c -static
/usr/local/bin/ld: /lib/../lib/libc.a(offtime.o): in function `__offtime':
(.text+0x3c): undefined reference to `__divmoddi4'
/usr/local/bin/ld: (.text+0xa2): undefined reference to `__divmoddi4'
/usr/local/bin/ld: (.text+0x22e): undefined reference to `__divmoddi4'
collect2: error: ld returned 1 exit status
[hjl@gnu-cfl-3 tmp]$ /usr/gcc-7.4.1-x32/bin/g++ -m32 x.c -static
[hjl@gnu-cfl-3 tmp]$=20

Since /lib/libc.a on Fedora 39 was compiled with GCC 13, it uses __divmoddi4
which was added to GCC 7 and GCC 6 won't be able to create static binary on
Fedora 39.  Why is static linking required here?
