Hello; Just FYI, beyond the STL/TR1 issues ...
It seems some of the recent changes broke configure for platforms that report themselves as "amd64" instead of "x86_64": ... checking for custom pack.lst... no checking build system type... Invalid configuration `amd64-portbld-freebsd9.1': machine `amd64-portbld' not recognized configure: error: /bin/sh ./config.sub amd64-portbld-freebsd9.1 failed ===> Script "configure" failed unexpectedly. ... There was a line in set_soenv.in that would do the adjustment but it doesn't seem to apply anymore. Regards, Pedro.
