Description M. MosG Gor. 2006-08-14 11:09:10 UTC
Can not compile CVS glibc 20060813 CVS HEAD

sysdeps/unix/sysv/linux/openat.c can not be compiled
with --enable-kernel=2.6.17 configure option:
  ...
../sysdeps/unix/sysv/linux/openat.c: In function '__OPENAT':
../sysdeps/unix/sysv/linux/openat.c:156: error: 'va_start' used in function with
fixed args
  ...

proposed solution: my diff for sysdeps/unix/sysv/linux/openat.c that
compiles and passes tests:
