which caused an error when the second header was dumped due to stdout
being closed.  Added test case 1066 to verify.  Also fixed a potential
problem where a closed file descriptor might be used for an upload
when more than one URL is given.

support is provided using WIN32 functions directly.

Improve HAVE_LONGLONG symbol description.

when including the OpenSSL header files. This is the recommended setting, this
prevents the undesired inclusion of header files with the same name as those
of OpenSSL but which do not belong to the OpenSSL package. The visible change
from previously released libcurl versions is that now OpenSSl enabled NetWare
builds also define USE_OPENSSL in config files, and that OpenSSL header files
must be located in a subdirectory named 'openssl'.

in curlbuild.h as CURL_SIZEOF_LONG. Definition now done from configure process
and in CVS curlbuild.h.dist for non-configure systems.

to have a curl_off_t data type no longer gated to off_t.

support this so it goes untested.

Factored out unslashquote. Added some 'const's in function parameters.

definition which might be defined in config.h or config-*.h files

now cause the definition of RECVFROM_TYPE_ARG2_IS_VOID, RECVFROM_TYPE_ARG5_IS_VOID
or RECVFROM_TYPE_ARG6_IS_VOID, as appropriate.

to the data type pointed by its respective argument and not the pointer type.

finds out its return type and the types of its arguments. Added definitions
for non-configure systems config files, and introduced macro sreadfrom which
will be used on udp sockets as a recvfrom() wrapper.

CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
handshake/connection is completed (typically SSL, TLS or SSH). By using this
you can figure out the application layer's own connect time. You can extract
the time stamp using curl's -w option and the new variable named
'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.

Fixed a file handle leak in the command line client if more than one
--stderr option was given.
