3e6c30a4b5 always return an 8-byte value (or void) from native functions called from Java 
This is important on the 32-bit OS X PowerPC ABI, since the location
of the low 32-bits of a return value change depending on whether the
entire value is 64-bits or not.

the branch.

6f1d02dae7 remove the libstdc++ dependency once and for all 
The trick is to make all destructors non-virtual.  This is safe because
we never use the delete operator, which is the only case where virtual
destructors are relevant.  This is a better solution than implementing
our own delete operator, because we want libraries loaded at runtime to
use the libstdc++ version, not ours.
