This is because mod-test.c shouldn’t use source code from lib, but it does need to include <config.h>. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/seccomp-filter.c, src/dynlib.h, src/lisp.h: * src/syssignal.h, src/sysstdio.h, src/systhread.h, src/tparam.h: Include <attribute.h>. * src/conf_post.h: Do not include <attribute.h>. All uses of attribute.h macros replaced with their _GL_ equivalents.
