renamed generated config.h to ares_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.

Refactor how libraries are checked for connect() function, follow-up.

Refactor how libraries are checked for connect() function,
and check for connect() as it is done for other functions.

sclose() function-like macro definition used to close a socket,
now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
config file preprocessor definitions.

check for socket() and closesocket() as it is done for other functions

Remove HAVE_CONFIG_H definition from here,
CFLAGS from common.dj already defines it.

initial step towards decoupling c-ares from libcurl for DOS

don't ignore these subdirs, they must be removed first

fix comment

Try to make more clear that --enable-curldebug has nothing to do with --enable-debug for this library.

Revert last change, it is inappropriate.

when running automake copy missing files instead of symlinking them

With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:

CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)

DEBUGBUILD used for debug enabled specific code (--enable-debug)

buildconf.bat is only for CVS tree builds.

archives. Used as a sentinel file in buildconf.bat to differentiate CVS builds.

Disable the '-export-symbols-regex' to discard this as the origin
of link failures related with shared libraries and non-GNU linkers.

c-ares Makefile.am back to using $(top_builddir) for *_LDADD

Use relative path to built c-ares tree libtool library

timeval struct on VMS when building with _XOPEN_SOURCE_EXTENDED undefined due
to definition taking place in socket.h instead of time.h
