cancellation variant for uClibc?

[Peter S. Mazinger]

Hello!

There are 2 ways to go with cancellation support
1. use wrapsyscall.c (provide visible __libc_x() in libc, x() in libc 
being not cancellable and use __libc_x() that in libpthread to provide x() 
cancellable (requires proper ordering of libs)
2. go the "NPTL/glibc" way and do the cancellation in libc already

old linuxthreads uses 1., nptl branch the latter (new linuxthreads done by 
me uses 1.)

Question to NPTL porters (users of 2.): why are functions duplicated in 
libpthread that are present in libc already (and are already cancellable)?

Opinions?

Thanks, Peter
