  Gnulib module: explicit_bzero
  
  The @code{explicit_bzero} function is an approximation to what is
  needed, and does not suffice in general to erase information.
  Although calling @code{explicit_bzero} should clear the memory in
  question, the information that was in memory may still be available
  elsewhere on the machine.  Proper implementation of information
  erasure requires support from levels below C code.
  
  Portability problems fixed by Gnulib:

  This function is missing on some platforms:
  glibc 2.24, FreeBSD 10, NetBSD 7.1, OpenBSD 5.4, macOS 10.12, Solaris 11.4, Android 9.0,
  and many other systems.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Although the module's implementation should clear the memory on
  platforms compatible with GCC and on platforms using traditional
  linkers, it may not clear the memory on non-GCC platforms that use
  whole-program optimization.
