* scripts/autogen.sh <--build-w32>: Support i686-w64-mingw32 and use
it by default if installed.

depending on compiler version.
(main): Use new macro.
* util/miscutil.c [!HAVE_TIMEGM]: Add prototype for the timegm

It seems that the LDAP keyserver helper build with the old mingw32
toolchain never worked correctly for LDAPS. The prototype there for
ldap_start_tls_s is plainly wrong for Windows. Anyway I included
special support so not to break building with the old compiler.
