Re: [ANNOUNCEMENT] GDB 8.2 released!

Building GDB 8.2 with MinGW GCC 7.3.0 on MS-Windows, I see a warning:

       CXX    record-btrace.o
     In file included from exceptions.h:23:0,
		      from utils.h:24,

					^~~~~~~~

Is this a real problem?

Also, a couple of places in remote-fileio.c use gettimeofday, which I
believe is deprecated under the recent versions of Posix; the
recommended replacement is clock_gettime.

Running the built GDB on itself produces the following warnings:

Anything here I should worry about?

Running "make -C gdb install-strip" fails:

     /bin/sh /d/gnu/gdb-8.2/install-sh -c -s ./contrib/gdb-add-index.sh \
	     d:/usr/test-gdb-8.2/bin/$transformed_name.exe
     d:\usr\bin\strip.exe:d:/usr/test-gdb-8.2/bin/_inst.8116_: file format not recognized

It fails because Makefile attempts to invoke 'strip' on a shell
script.  I couldn't find any way to get past that except by hacking
gdb/Makefile to remove the offending portion, then installing that
shell script manually.  How does this work on Posix hosts?

Thanks.
