+dnl ----------------------
+dnl On a few platforms, the compiler and/or loader nags with untruthful
+dnl comments stating that "most" uses of strcat/strcpy/sprintf are incorrect,
+dnl and implying that most uses of the recommended alternatives are correct.
+dnl
+dnl Factually speaking, no one has actually counted the number of uses of these
+dnl functions versus the total of incorrect uses.  Samples of a few thousand
+dnl instances are meaningless compared to the hundreds of millions of lines of
+dnl existing C code.
+dnl
+dnl strlcat/strlcpy are (as of 2012) non-standard, and are available on some
+dnl platforms, in implementations of varying quality.  Likewise, snprintf is
+dnl standard - but evolved through phases, and older implementations are likely
+dnl to yield surprising results, as documented in manpages on various systems.
