made it an unsigned int. The type was only used in the curl_sockaddr struct definition (only used by the curl_opensocket_callback). On all platforms I could find information about, socklen_t is 32 unsigned bits large so I don't think this will break the API or ABI. The main reason for this change is of course for all the platforms that don't have a socklen_t definition in their headers to build fine again. Providing our own configure magic and custom definition of socklen_t on those systems proved to work but was a lot of cruft, code and extra magic needed - when this very small change of type seems harmless and still solves the missing socklen_t problem. |

Include files for libcurl, external users.
They're all placed in the curl subdirectory here for better fit in any kind
of environment. You should include files from here using...
#include <curl/curl.h>
... style and point the compiler's include path to the directory holding the
curl subdirectory. It makes it more likely to survive future modifications.
NOTE FOR LIBCURL HACKERS
All the include files in this tree are written and intended to be installed on
a system that may serve multiple platforms and multiple applications, all
using libcurl (possibly even different libcurl installations using different
versions). Therefore, all header files in here must obey these rules:
* They cannot depend on or use configure-generated results from libcurl's or
curl's directories. Other applications may not run configure as (lib)curl
does, and using platform dependent info here may break other platforms.
* We cannot assume anything else but very basic compiler features being
present. While libcurl requires an ANSI C compiler to build, some of the
earlier ANSI compilers clearly can't deal with some preprocessor operators.
* Newlines must remain unix-style for older compilers' sake.
* Comments must be written in the old-style /* unnested C-fashion */
To figure out how to do good and portable checks for features, operating
systems or specific hardwarare, a very good resource is Bjorn Reese's
