Hi.
In order to make GCC 4.1 happy and build current tip, we need to define
static constants out of a class definition.
Ready for trunk?
Thanks,
Martin
gcc/ChangeLog:
2018-07-03 Martin Liska <mli...@suse.cz>
* tree-switch-conversion.h (struct jump_table_cluster): Define
constant values outside of class declaration.
