When using Sun C compiler the preprocessor somehow inserts an extra space
in front of replaced symbol, breaking CURL_CHECK_DEF macro. To workaround
this, macro CURL_CHECK_DEF now ignores all leading whitespace in front of
symbol substitution result.

The purpose of the whole patch was to silence a compiler warning triggered
with GCC 4 on file ares_process.c The specific compiler warning was
'dereferencing type-punned pointer might break strict-aliasing rules'.
A simpler patch will follow to equally silence the warning.
AIX, at least, does not have sockaddr_storage.ss_family member.
Detect this in the configure logic and use proper #ifdefs in the
ares_process logic.

If option is specified, it will be honored independant of the
--(dis|en)able-debug option.
If option is not specified, it will follow --(dis|en)able-debug
setting, whose default is disabled if not specified.
Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. But,
autoconf 2.62 version of AC_AIX defines _ALL_SOURCE along with other four
preprocessor symbols no matter if the system is AIX or not. To keep the
traditional behaviour, as well as an uniform one, across autoconf versions
AC_AIX is replaced with our own internal macro.

provides. We only need to include our m4/reentrant.m4 file in acinclude.m4

that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
macro when checking monotonic clock availability. This is now fixed and the
monotonic clock will not be used unless the feature test macro is defined
with a value greater than zero indicating always supported.
enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.
