[Bug libgcj/15713] New: compile interpret.cc with -fno-strict-aliasing

[tromey at gcc dot gnu dot org]

we should either fix interpret.cc or compile it with
-fno-strict-aliasing.  Andrew points out that 
it has code like this in it:

  jbyte value = (*(jint*)&rvalue) & 0xff;

Confirmed, it would look nicer if you used a union also as then you can refer to the types by nice 
variable names like double_value and such like that.

This is in _Jv_InterpMethod::run.
