Well, the new glibc-2.4 only supports nptl, unlike glibc-2.3 which supported both threading models. So if you want legacy linuxthreads, you have to stay with glibc-2.3. As for being "better", glibc-2.4 is better than 2.3 IMHO. Also, "nptl -nptlonly" combination with 2.3 actually builds two versions of glibc, one with nptl and one with linuxthreads, so you get a longer compile and larger disk footprint. Regards, Jure
