ok, it seems that newlib/libc/stdlib/environ.c has not made its way
into cygwin1.dll and/or libcygwin.a; shouldn't that be included?

environ is the exported symbol referencing the internal __cygwin_environ
variable on x86_64.  Linking against and accessing it works for me:

  $ uname -a
  CYGWIN_NT-6.2 VMBERT864 1.7.21(0.266/5/3) 2013-06-11 21:43 x86_64 Cygwin
  $ cat > envtest.c <<EOF
  #include <stdio.h>

  int
  main ()
  {
    extern char **environ;

    printf ("environ: %p first entry: <%s>\n", &environ, environ[0]);
    return 0;
  }
  EOF
  $ gcc -o envtest envtest.c
  $ ./envtest
  environ: 0x1802a4778 first entry: <ALLUSERSPROFILE=C:\ProgramData>
