secure_getenv is broken on FreeBSD.

[Mats Erik Andersson]

Hello there,

the recent module "secure_getenv" is broken on FreeBSD 8.2 and 9.0.
Extracting from [1] gives the essence:

  gcc ... -c secure_getenv.c
  In file included from ./unistd.h:114,
                   from ./stdlib.h:96,
                   from secure_getenv.c:18:
  ./getopt.h:199: error: redefinition of 'struct option'

Clearly the implementation is not protecting previous inclusions
sufficiently diligently.

On behalf og GNU Inetutils,

   Mats Erik Andersson
