With a workaround for the ipc_perm/mode issue, I can reproduce the
C++98 does not have long long int, and does not use (unsigned) long
long int for hexadecimal literals. So let's use an ULL suffix here,
which is still not strict C++98, but which works with more compilers.

Sometimes, we need to copy a section name from one decl or symtab node
