Dear libnatpmp-dev maintainer, please check out https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1050766 where classified-ads fails to build due to missing natpmp_declspec.h with version 20230423-1 of libnatpmp-dev. I don't see any package providing the missing file natpmp_declspec.h, is there any hope?
-- Antti, having package not compiling
