[Moore, Robert]

I have some questions about this entire issue:

+ * Some compilers can handle designated initializers, which is needed
+ * under Linux kernel builds for structures that are entirely function
* pointers.

I don't understand why this is coming up now, since ACPICA has been integrated with Linux for something like the last 15 years. It's the "which is needed under Linux kernel builds" wording that concerns me the most. Are you saying that the ACPICA build for Linux is broken and does not work?

Further, there are quite a few similar dispatch tables in ACPICA, why are these not a problem?
