Yesterday in the night I made threads in Gwydion Dylan work, at least sort of. Now I have to find a way to implement thread-local variables, write standards-compliant wrappers for threads and mutexes, and last, but not least, modify the build system to recognize the platforms where threads are available.
Also, it seems that I've found the bug in the .spec file that was responsible for the broken RPMs. You'd guess someone would tell me that they are broken a little earlier.
