If building GnuPG for Win32 with OpenLDAP instead of Win32's wlpda32, the wrong
header file is being included.

From configure:
configure: creating cache config.cache
checking build system type... i686-pc-mingw32
checking host system type... i686-pc-mingw32
checking whether LDAP via "-lldap" is present and sane... no
checking whether I can make LDAP be sane with lber.h... yes
checking for ldap_get_option... yes
checking for ldap_set_option... yes
checking for ldap_start_tls_s... yes

$ make
gcc  -O3 -s -mms-bitfields -march=pentium3 -Wall -Wcast-align -Wshadow
-Wstrict-prototypes -Wformat-nonliteral -o gpgkeys_ldap.exe
gpgkeys_ldap-gpgkeys_ldap.o gpgkeys_ldap-ksutil.o ../util/libcompat.a  -lldap

The 'A' suffixed names are supplied by winldap.h, but that should only be
included if also linking with wldap32.dll.

I couldn't think of a non-fugly way to fix the source.

The section of keyserver/gpgkeys_ldap.c is
#ifdef _WIN32
#include <winsock2.h>
#include <winldap.h>
#ifdef NEED_LBER_H
#include <lber.h>
/* For OpenLDAP, to enable the API that we're using. */
#include <ldap.h>

Also, if including winsock2.h, shouldn't the linking be with -lws2_32 instead of
