--- Comment #15 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-10-07 23:03:09 UTC --- Note that the autoconf test is built by the C++ compiler, thus there is no real difference between timespec and struct timespec. In general, remember that library patches should always go to the libstdc++ mailing list too (Jon is probably the best person to review changes in this area and he doesn't track gcc-patches much, AFAIK)
