is for the TCP connect. I changed it to TIMER_PRETRANSFER which seems to be
what was intended here.

in regard to C standard, third party libraries and operating systems etc.

  libraries are supported. Starting now, each underlying SSL library support
  code does a set of defines for the 16 functions the generic layer (sslgen.c)
  uses (all these new function defines use the prefix "curlssl_"). This
  greatly simplified the generic layer in readability by involving much less
  #ifdefs and other preprocessor stuff and should make it easier for people to
  make libcurl work with new SSL libraries.

  Hopefully I can later on document these 16 functions somewhat as well.

  I also made most of the internal SSL-dependent functions (using Curl_ssl_
  prefix) #defined to nothing when no SSL support is requested - previously
  they would unnecessarily call mostly empty functions.

function(pointer to char,int,int,pointer to void)' is compiler dependent

  functionality killed it due to its unconditional use of
  X509_STORE_set_flags...

  All boolean options (such as -O, -I, -v etc), both short and long versions,
  now always switch on/enable the option named. Using the same option multiple
  times thus make no difference. To switch off one of those options, you need
  to use the long version of the option and type --no-OPTION. Like to disable
  verbose mode you use --no-verbose!

- Added --remote-name-all to curl, which if used changes the default for all
  given URLs to be dealt with as if -O is used. So if you want to disable that
  for a specific URL after --remote-name-all has been used, you muse use -o -
  or --no-remote-name.

- Updated main.c to return CURLE_OK if PARAM_HELP_REQUESTED was returned
  from getparameter instead of CURLE_FAILED_INIT.  No point in returning
  an error if --help or --version were requested.
