+Subject: [PATCH] SystemInformation: Include backtrace-related headers on
+ FreeBSD
+
+This was probably broken for a long while, but the problem was not apparent
+because the check for execinfo.h would fail by default because
+-I/usr/local/include was not being passed to the compiler when making the
+checks for the header's existence.
+
+Now that very recent FreeBSD versions (ie. 10-CURRENT) have NetBSD's
+libexecinfo in base (and it is thus installed into /usr), the
+backtrace-related checks would pass, but the required headers were not being
+included in SystemInformation.cxx.
