 # A patch discussed here:
 #      https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.html
+#
 # introduces spurious #line markers into the preprocessor output.  The result
 # appears in gcc 5.0 and (with modification) in 5.1, making it necessary to
 # determine if we are using gcc, and if so, what version because the proposed
 # solution uses a nonstandard option.
+#
+# As illustrated in
+#      https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60723
+#
+# gcc developers chose to ignore the problems with this, and summarized those
+# as "intriguing problems" in
+#      https://gcc.gnu.org/gcc-5/porting_to.html
