 2.  Doug Hardie's code to change the way tokens are parsed when
     processing configuration files.  Now properly handling quoted

     error; entire configuration file is now processed and
     all errors reported in one pass.


Changes from 4.1.a7 to 4.1.b8:
------------------------------
 1.  Added more checks to try and find getprpwnam().
 2.  Fixed bug that enabled pam by default (it should

     to Derek Chan for reporting this bug).

 8.  Guard strlcpy and strlcat so they aren't compiled if the
     platform supplies them.
 9.  Fix problem with default pam values on MacOS X.
10.  Fix pop_parse.c compilation errors on some compilers.
11.  Fix crash if mangle string ended with header and no ")".

Changes from 4.1.a6 to 4.1.a7:
------------------------------
 1.  Tweaked pam so that default isn't enabled accidently.
 2.  Added check for getprpwnam() and if found, enable
     specialauth, just like we do for getspnam().  This
     should fix default configuration on platforms like
     Tru64 (thanks to J Bacher for his help on this).

------------------------------
 1.  Updated IPv6 support (thanks to Hajimu UMEMOTO).
     - Check for socklen_t

     - narrow the IPv6-specific chunk by defining struct addrinfo
     - when it is not available.
     - check the return value of socket() correctly.
     - a socket have to be closed when bind fails.
     - chase SO_KEEPALIVE addition to an IPv4 logic.
 2.  Correct milliseconds calculation (thanks to Jose Marcio
     Martins da Cruz for the patch).
