+modernize-deprecated-headers
+==========================
+
+Some headers from C library were deprecated in C++ and are no longer welcome in
+C++ codebases. For more details refer to the C++ 14 Standard [depr.c.headers]
+section.
+
+This check replaces C standard library headers with their C++ alternatives.
+
+Improtant note: the Standard doesn't guarantee that the C++ headers declare all
+the same functions in the global namespace. The check in its current form can
+break the code that uses library symbols from the global namespace.
+
+* `<assert.h>`
+* `<complex.h>`
+* `<ctype.h>`
+* `<errno.h>`
+* `<fenv.h>`     // deprecated since C++11
+* `<float.h>`
+* `<inttypes.h>`
+* `<iso646.h>`
+* `<limits.h>`
+* `<locale.h>`
+* `<math.h>`
+* `<setjmp.h>`
+* `<signal.h>`
+* `<stdalign.h>` // deprecated since C++11
+* `<stdarg.h>`
+* `<stdbool.h>`  // deprecated since C++11
+* `<stddef.h>`
+* `<stdint.h>`
+* `<stdio.h>`
+* `<stdlib.h>`
+* `<string.h>`
+* `<tgmath.h>`   // deprecated since C++11
+* `<time.h>`
+* `<uchar.h>`    // deprecated since C++11
+* `<wchar.h>`
+* `<wctype.h>`
+
+If the specified standard is older than C++11 the check will only replace
+headers deprecated before C++11, otherwise -- every header that appeared in
+the list.
