  Gnulib module: strftime-fixes
  @mindex strftime-fixes
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On native Windows platforms (mingw, MSVC), this function works incorrectly
  when the environment variable @env{TZ} has been set by Cygwin.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  The %c specifier does not work with a time retrieved through @code{gmtime}
  or @code{gmtime_r}, since it outputs also the current time zone,
  on some platforms:
  glibc 2.30, NetBSD 10.0, Solaris 11.4.
  @item
  The %c specifier produces no weekday name and no month name, only a
  potentially ambiguous numerical output, on some platforms:
  mingw, MSVC.
  @item
  The %h specifier produces empty output on some platforms:
  mingw, MSVC.
  @item
  The %r specifier produces empty output on some platforms:
  mingw, MSVC.
  @item
  The %r specifier produces empty output, at least in a French locale,
  on some platforms:
  macOS 12.5, FreeBSD 14.0.
  @item
  The %r specifier includes an AM/PM indicator, at least in a French locale,
  on some platforms:
  NetBSD 10.0, Solaris 11.4.
  @item
  The %p specifier produces non-empty output, at least in a French locale,
  on some platforms:
  NetBSD 10.0, Solaris 11.4.
  @item
  The Windows C runtime library (which is used by MinGW) does not
  support the %e specifier (and possibly the other more recent SUS
  specifiers too, i.e., %C, %D, %h, %n, %r, %R, %t, and %T).
  @item
  Native Windows platforms (mingw, MSVC) support only a subset of time
  zones supported by GNU or specified by POSIX@.  @xref{tzset}.
  @end itemize
  
  @mindex nstrftime
  Extension: Gnulib offers a module @samp{nstrftime} that provides an
  @code{nstrftime} function with various GNU extensions.
