  POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9799919799/functions/strdup.html}
  
  Gnulib module: strdup or strdup-posix
  @mindex strdup
  @mindex strdup-posix
  
  Portability problems fixed by either Gnulib module @code{strdup} or @code{strdup-posix}:
  @itemize
  @item
  This function has no prototype in @code{<string.h>} on some old platforms.
  @end itemize
  
  Portability problems fixed by Gnulib module @code{strdup-posix}:
  @itemize
  @item
  On some platforms, when the function fails it does not set @code{errno}:
  mingw, MSVC 14.
  
  @item
  On some platforms, when the function fails it might set @code{errno}
  to @code{EAGAIN} instead of to @code{ENOMEM}. Although POSIX allows
  @code{EAGAIN}, the @code{strdup-posix} module insists on @code{ENOMEM}
  which also conforms to POSIX and is GNU-compatible:
  Solaris 11.4.
