+Subject: [PATCH] gdb: fix gnu-nat build
+Content-Transfer-Encoding: 8bit
+Content-Type: text/plain; charset=UTF-8
+
+When building gnu-nat.c, we get:
+
+      CXX    gnu-nat.o
+    gnu-nat.c: In member function 'virtual void gnu_nat_target::create_inferior(const char*, const string&, char**, int)':
+    gnu-nat.c:2117:13: error: 'struct inf' has no member named 'target_is_pushed'
+     2117 |   if (!inf->target_is_pushed (this))
+          |             ^~~~~~~~~~~~~~~~
+    gnu-nat.c:2118:10: error: 'struct inf' has no member named 'push_target'
+     2118 |     inf->push_target (this);
+          |          ^~~~~~~~~~~
+
+This is because of a confusion between the generic `struct inferior`
+variable and the gnu-nat-specific `struct inf` variable.  Fix by
+referring to `inferior`, not `inf`.
+
+Adjust the comment on top of `struct inf` to clarify the purpose of that
+type.
