Hi Ralf, I'd welcome patches to modernize the m4/*.m4 files under my care. Since I tend to use gnulib's files as models, it's worthwhile to update them to use macros that aren't listed as "obsolete". Here are some of the affected uses: $ grep -li meyering modules/*|xargs grep -hF .m4|xargs grep AC_TRY_RUN m4/fsusage.m4: [AC_TRY_RUN([ m4/fsusage.m4: [AC_TRY_RUN([ m4/fsusage.m4: [AC_TRY_RUN([#include <sys/types.h> m4/fsusage.m4: [AC_TRY_RUN([#include <sys/types.h> m4/fsusage.m4: [AC_TRY_RUN([#include <sys/types.h> m4/link-follow.m4: AC_TRY_RUN( m4/mkdir-slash.m4: AC_TRY_RUN([ m4/rename.m4: AC_TRY_RUN([ m4/rename-dest-slash.m4: AC_TRY_RUN([ m4/rmdir-errno.m4: AC_TRY_RUN([ m4/utimes-null.m4:AC_TRY_RUN([
