+ * mi-main.c (register_changed_p, get_register): Use alloca()
+ to allocate space previously allocated via gcc's
+ variable-length array extension.
+ (mi_cmd_data_write_register_values, mi_cmd_data_write_memory):
+ Change type of ``buffer'' to ``void *''. Don't cast return value
+ from xmalloc(). Add a cleanup to free the xmalloc'd buffer.

* mi-main.c (mi_cmd_data_evaluate_expression): Replace value_ptr
