dnl In autoconf 2.5x, AC_OUTPUT is replaced by four AC_CONFIG_* macros,
dnl which can all be called multiple times as needed, plus one (different)
dnl AC_OUTPUT macro. This one lists the files to be created:
-AC_CONFIG_FILES( \
- Makefile \

- )
+AC_CONFIG_FILES(Makefile)
AC_CONFIG_FILES([scripts/testsuite_flags],[chmod +x scripts/testsuite_flags])
-dnl These commands are run at the end of config.status:
-AC_CONFIG_COMMANDS([default],
-[if test -n "$CONFIG_FILES"; then
- # Multilibs need MULTISUBDIR defined correctly in certain makefiles so
- # that multilib installs will end up installed in the correct place.
- # The testsuite needs it for multilib-aware ABI baseline files.
- # To work around this not being passed down from config-ml.in ->
- # srcdir/Makefile.am -> srcdir/{src,libsupc++,...}/Makefile.am, manually
- # append it here. Only modify Makefiles that have just been created.
- #
- # Also, get rid of this simulated-VPATH thing that automake does.
