+Subject: [PATCH] amd64-linux-siginfo.c: Adjust include order to avoid gnulib
+ error
+
+On Fedora rawhide, after updating to glibc-2.33, I'm seeing the
+following build failure:
+
+  CXX    nat/amd64-linux-siginfo.o
+In file included from /usr/include/bits/sigstksz.h:24,
+                 from /usr/include/signal.h:315,
+                 from ../gnulib/import/signal.h:52,
+                 from /ironwood1/sourceware-git/rawhide-gnulib/bld/../../worktree-gnulib/gdbserver/../gdb/nat/amd64-linux-siginfo.c:20:
+../gnulib/import/unistd.h:663:3: error: #error "Please include config.h first."
+  663 |  #error "Please include config.h first."
+      |   ^~~~~
+
+glibc-2.33 has changed signal.h to now include <bits/sigstksz.h> which,
+in turn, includes <unistd.h>. For a gdb build, this causes the gnulib
+version of unistd.h to be pulled in first.  The build failure shown
+above happens because gnulib's config.h has not been included before
+the include of <signal.h>.
+
+The fix is simple - we just rearrange the order of the header file
+includes to make sure that gdbsupport/commondefs.h is included before
+attempting to include signal.h.  Note that gdbsupport/commondefs.h
+includes <gnulib/config.h>.
+
+Build and regression tested on Fedora 33.  On Fedora rawhide, GDB
+builds again.
