Back to GCC hacking. The patch for bug 13092 is finally accepted and committed to the mainline.
I work on member class as template friend feature to compliment the work earlier on member function. It can deal with simpler cases now, but some more thought is necessary for advanced cases. May be a few week to go before a patch is ready.
As a break, I look at a few template template parameter bugs reported. Fixing them is not as hard as the template friend feature above and take only a day or two each. In fact one is fixed already and I am testing a patch for the next one.
