I spent the day trying to debug why libjava fails to build on this system
with the new glibc.  It seems that scandir is broken on 64-bit kernels.
There seems to be an off by one error in copying dirent structs.  Either
the define in <dirent.h> for _D_ALLOC_NAMLEN is wrong or the kernel
sometimes returns a value for d_reclen that is sometimes too small.  The
code in fs/readdir.c suggests that sys_parisc32.c needs fixing.

The enclosed seems to fix both the libjava build and the svn problem.
Kyle's branch uses ALIGN instead of ROUND_UP.
