Only the first one listed is managed by : autoheader. Additional ones can be based on hand-maintained : substitution headers. The first configuration header can simply be : ignored by the software and be informative only. : : AC_CONFIG_HEADERS([discard_config.h system_config.h user_config.h]) Thanks. This looks like the path to a solution :) I'd just use a special tag description on the defines that should be filtered from system_config.h and create a sed script that creates system_config.h.in from discard_config.h.in to avoid having defines multiple places. Something like that. Multiple definitions gives out warnings BTW on a lot of compilers... The reason I want this is because the sources also comes with Visual Studio project files. For those, the system_config.h is pregenerated, but with the project files it's impossible to do any package configuration, so VC++ users will need to edit one header file manually if they want to change the build options...
