This is mainly useful to work around possible bugs in the optional resolver libraries (as of now ADNS). Note that on Windows there is no code to use systems's resolver and thus for full functionality dirmngr must be build with a separate resolver. This patch also does way with configure options to disable the use of CERT and SRV records. Signed-off-by: Werner Koch <[email protected]>
