+When building with reconfigure=no, the build fails as follows.
+
+  libgpsd_core.c: In function 'gpsd_poll':
+  libgpsd_core.c:1236:35: error: 'const struct gps_type_t' has no member named 'mode_switcher'
+  scons: *** [libgpsd_core.os] Error 1
+  scons: building terminated because of errors.
+  make: *** [/scratch/peko/build/gpsd-3.10/.stamp_built] Error 2
+
+For an example, see the following autobuild failure.
+
+  http://autobuild.buildroot.net/results/424/42409545547daddd77c9e9bd59474ed033834ad5/
+
+The problem appears to be a failure to protect the mode_switcher field with
+a RECONFIGURE_ENABLE ifdef.
