I have my doubts if a cygwin binary can access the native (non-cygwin)
Oracle libraries easily.

I'm not that versed in cygwin specifics, but as it seems your dependant
libraries are only available in static form.

IIRC Corinna (the syslog-ng maintainer on cygwin) mentioned something
about a libtool version that has problems on cygwin. You might need to
regenerate the configure/Makefile/libtool scripts using the cygwin
supplied tools.

I know that syslog-ng could successfully be compiled on cygwin, and I
think that libdbi core could probably too. But compiling
libdbi-drivers/oracle will not be easy.

This might help though:
