It seems that the Jamfile for the date-time regression tests is making GCC 2.95.x regression testing fail with this: /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:1585: in find-compatible-subvariant *** argument error * rule split-target-subvariant ( target-var properties-var toolset-var variant-var : subvariant ) * called with: ( sv-target sv-properties sv-toolset sv-variant : ) * missing argument subvariant /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:2032:see definition of rule 'split-target-subvariant' being called /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:1654: in link-libraries /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:1857: in generate-dependencies /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:1964: in subvariant-target /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:2057: in main-target /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/boost-base.jam:1369: in declare-local-target /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/testing.jam:64: in boost-test /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/testing.jam:552: in run Jamfile:218: in load-jamfiles /.automount/magrathea/root/home/user3/dgregor/Projects/boost/tools/ build/v1/bootstrap.jam:21: in boost-build /.automount/magrathea/root/home/user3/dgregor/Projects/boost/boost- build.jam:16: in module scope The following patch, which I've already applied, seems to fix the problem. However, that USE_DATE_TIME_PRE_1_33_FACET_IO define seems rather strange to me; is that really what was intended for the serialization tests?
