--- Comment #5 from Tadeus Prastowo <tadeus.prastowo at unitn dot it> --- Created attachment 46466 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46466&action=edit Complete terminal output during the non-parallel build after applying the patchset I confirm that your patchset solves the build problem. Specifically, applying your patchset to the release tarball of GCC 9.1.0 (see https://gcc.gnu.org/ml/gcc/2019-05/msg00024.html) fails for the `ChangeLog' and `configure'. Nevertheless, the build is successful since I think the changes to those two files are not essential. Attached is the complete terminal output during the successful non-parallel build after successfully applying your patchset for the files `Makefile.am' and `Makefile.in'.
