+Subject: [PATCH] gdbserver: fix build for m68k
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
+the build fails on m68k with the following diagnostics:
+
+In file included from ./../nat/linux-ptrace.h:28:0,
+                 from linux-low.h:27,
+                 from linux-m68k-low.c:20:
+[...]/usr/include/sys/reg.h:26:3: error: expected identifier before numeric constant
+   PT_D1 = 0,
+   ^
+[...]usr/include/sys/reg.h:26:3: error: expected « } » before numeric constant
+[...]usr/include/sys/reg.h:26:3: error: expected unqualified-id before numeric constant
+In file included from linux-m68k-low.c:27:0:
+[...]usr/include/sys/reg.h:99:1: error: expected declaration before « } » token
+ };
+ ^
+
+Fix this by moving <sys/reg.h> on top of "linux-low.h".
