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'.

remain in use as internal curl_off_t print formatting strings for the internal
*printf functions which still cannot handle print formatting string directives
such as "I64d", "I64u", and others available on MSVC, MinGW, Intel's ICC, and
other DOS/Windows compilers.

This reverts previous commit part which did:

FORMAT_OFF_T  -> CURL_FORMAT_CURL_OFF_T
FORMAT_OFF_TU -> CURL_FORMAT_CURL_OFF_TU

was discovered to be problematic while investigating an incident reported by
Von back in May.  curl in this case doesn't include a Content-Length: or
Transfer-Encoding: chunked header which is illegal. This test case is
added to DISABLED until a solution is found.

the names of the curl_off_t formatting string directives now become
CURL_FORMAT_CURL_OFF_T and CURL_FORMAT_CURL_OFF_TU.

CURL_FMT_OFF_T  -> CURL_FORMAT_CURL_OFF_T
CURL_FMT_OFF_TU -> CURL_FORMAT_CURL_OFF_TU

Remove the use of an internal name for the curl_off_t formatting string directives
and use the common one available from the inside and outside of the library.

FORMAT_OFF_T  -> CURL_FORMAT_CURL_OFF_T
FORMAT_OFF_TU -> CURL_FORMAT_CURL_OFF_TU

suffixes, using a test-and-try suffix approach letting the compiler validate it.

the source code of curlx_strtoll is excluded if NEED_CURL_STRTOLL isn't defined.

Add debug tracing for CURL_CHECK_DEF_INTXX_C.

155 - bug #2038004 "Curl OpenSSL not compatible with 7.17 or 7.18"

156 - proxy CONNECT issue (details not public yet due to possible security impact)

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