  # Allow the C++ wrappers around C files.  Without these mappings,
  # if you #include <cstdio>, iwyu will tell you to replace it with
  # <stdio.h>, which is where the symbols are actually defined.  We
  # inhibit that behavior to keep the <cstdio> alone.  Note this is a
  # public-to-public mapping: we don't want to *replace* <assert.h>
  # with <cassert>, we just want to avoid suggesting changing
  # <cassert> back to <assert.h>.  (If you *did* want to replace
  # assert.h with cassert, you'd change it to a public->private
  # mapping.)  Here is how I identified the files to map:
  # $ for i in /usr/include/c++/4.4/c* ; do ls /usr/include/`basename $i | cut -b2-`.h /usr/lib/gcc/*/4.4/include/`basename $i | cut -b2-`.h 2>/dev/null ; done
  #
  # These headers are defined in C++14 [headers]p3.  You can get them with
  # $ sed -n '/begin{floattable}.*{tab:cpp.c.headers}/,/end{floattable}/p' lib-intro.tex | grep tcode | perl -nle 'm/tcode{<c(.*)>}/ && print qq@  { include: [ "<$1.h>", public, "<c$1>", public ] },@' | sort
  # on https://github.com/cplusplus/draft/blob/master/source/lib-intro.tex
