RFA 0/2 fix for bug with large structure offsets

[Jan Kratochvil]

Hi,

I have posted for this patchset:

https://sourceware.org/bugzilla/show_bug.cgi?id=17520#c1

Fedora carries for it the patchset:

It was concluded that patching it before GDB is switched to C++ would be fragile as there cannot be done easy sanity checking if the inferior types width has not regressed.  With C++ one can wrap the offset types into sanity-checked classes with overriden operators.

But the GDB switch to C++ takes too many years.
