So if you want legacy linuxthreads, you have to stay= =20 with glibc-2.3. As for being "better", glibc-2.4 is better than 2.3 IMHO.=20 Also, "nptl -nptlonly" combination with 2.3 actually builds two versions of= =20 glibc, one with nptl and one with linuxthreads, so you get a longer compile= =20 and larger disk footprint.
