We should first make clear ordering issues. As for PTR_MANGLE a generic
comes before PTR_MANGLE is defined so we need extra undef before each
definition.
With file included as last these will not be needed.
Also when we expand this I am bit afraid of inconsistencies when half
can be defined before this file and other half after it is included.
