For now, I rebuilt only Binutils 2.32 with the patch.  The patch seems to be
working, in the sense that the section flags are now different:

D:\usr\eli>objdump -h -j .gnu_debuglink ./hello.exe

./hello.exe:     file format pei-i386

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  8 .gnu_debuglink 00000014  00416000  00416000  00004c00  2**2
                  CONTENTS, READONLY, DEBUGGING

Is this DEBUGGING flag expected to be there?  Because with it, stock GDB 8.2
still emits the warning; removing the flag also removes teh warning, as before.
 This flag is not shown on GNU/Linux, as I reported above.

I will rebuild GDB tomorrow and wee if that fixes the problem.

Will do if the problem remains after rebuilding GDB.

Thanks.
