It is similar to my first patch:

http://sources.redhat.com/ml/libc-alpha/2001-07/msg00223.html

It will cause posix/tst-regex to fail:

# ldd posix/tst-regex
        librt.so.1 => /lib/librt.so.1 (0x40024000)
        libc.so.6 => /lib/libc.so.6 (0x40036000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x40168000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

With your patch, all programs linked with librt will have the 2MB stack
limit. For the initial thread, the limit is not necessary. My second
patch tries to call __pthread_init_max_stacksize when we know the
stack limit will make a difference:

http://sources.redhat.com/ml/libc-alpha/2001-07/msg00224.html

It may not be the best approach, but posix/tst-regex works.
