Original wording could lead users in thinking it tries to
somehow parse the filename for a date expression (like
news_2012_03_05.html). It never mentions that it actually
reads the mtime of the file in filesystem.

This allows building of libcurl on DOS using DJGPP 2.04 and Watt-32
sockets. I know there's already Makefile.djgpp, but I find this more
convenient since I'm used to using the ./configure script from other
platforms

The commit e650dbde that stripped off [brackets] from ipv6-only host
headers for the sake of cookie parsing wrongly incremented the host
pointer which would cause a bad free() call later on.

The refactoring of HTTP CONNECT handling in commit 41b02378 that
made it protocol independent broke it for the multi interface. This fix
now introduce a better state handling and moved some logic to the
http_proxy.c source file.

Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also
consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or
(_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.

Use fopen() with "w" mode instead of "wt" to fix cygwin builds.

Windows standard libraries are located in C:/Program Files/Microsoft
SDKs/[...]. They are already included in the default MSVC
LIBPATH. Hence, find_library(WSOCK32_LIBRARY wsock32) and
find_library(WS2_32_LIBRARY ws2_32) are not needed. They return the full
path to the libraries including spaces. Of course,
list_spaces_append_once will mangle the result and the build fails.

If the Curl_ipv6works() function says no, there is no reason to try AAAA
names even if libcurl was built with IPv6 support enabled.

Bug: http://curl.haxx.se/mail/lib-2012-03/0045.html

Changed the returned curl error codes for EHLO and HELO responses from
CURLE_LOGIN_DENIED to CURLE_REMOTE_ACCESS_DENIED as a negative response
from these commands represents no service as opposed to a login error.

Since the host name is passed in to the cookie engine it will not work
correctly if the brackets are left in the name.

An alternative would be:

1. specify HTTPS_CA_DIR and/or HTTPS_CA_FILE
2. ensure that Net::SSL is being used, and IO::Socket::SSL is NOT being
   used

This question and answer explain:

Curl_protocol_connect() now does the tunneling through the HTTP proxy if
requested instead of letting each protocol specific connection function
do it.

The check for Winsock definition was a bit too broad
