I just tested the new implementation from git, and gcc fails to build
libsyslog-ng-patterndb.dll.a since a lot of function calls are missing:

  libtool: link: gcc -std=gnu99 -shared  .libs/radix.o .libs/patterndb.o \
.libs/timerwheel.o .libs/patternize.o   -lssl -lcrypto -lz -lrt \
/usr/lib/libgmodule-2.0.dll.a -L/usr/lib /usr/lib/libglib-2.0.dll.a \
/usr/lib/libintl.dll.a /usr/lib/libiconv.dll.a /usr/lib/libevtlog.dll.a -lresolv \
/usr/lib/libpcre.dll.a  -O2 -Wl,--export-all-symbols   -o \
.libs/cygsyslog-ng-patterndb-0.dll -Wl,--enable-auto-image-base -Xlinker --out-implib \
-Xlinker .libs/libsyslog-ng-patterndb.dll.a  Creating library file: \
                .libs/libsyslog-ng-patterndb.dll.a
  .libs/radix.o: In function `r_new_pnode':
  modules/dbparser/radix.c:374: undefined reference to `_log_msg_get_value_handle'
  modules/dbparser/radix.c:618: undefined reference to `_msg_limit_internal_message'
  modules/dbparser/radix.c:618: undefined reference to `_log_msg_get_value_name'
  modules/dbparser/radix.c:618: undefined reference to `_msg_event_create'
  modules/dbparser/radix.c:629: undefined reference to `_msg_limit_internal_message'
  modules/dbparser/radix.c:567: undefined reference to `_msg_event_create'
  modules/dbparser/radix.c:674: undefined reference to `_msg_limit_internal_message'
  modules/dbparser/radix.c:674: undefined reference to `_msg_event_create'

etc.

The reason is that the dependency to libsyslog is missing.  Would you mind
to apply this simple patch?  It fixes the build problem and the resulting
pdbtool appears to work fine.
