Patch 5 deals with ISO C errors emitted by tests when the large memory model is used. size_t and ptrdiff_t are __int20 with -mlarge, and if the test is compiled with -pedantic-errors and -std=* or -ansi, then use of these types causes an error of the form: ISO C does not support __int20 types I fixed this by adding dg-prune-output directives to tests which cause this error.
Alternatively, I considered adding typedefs preceded by __extension__ to fix these errors, but in many cases __SIZE_TYPE__ is directly used so replacing all these with a new typedef'd type changes the code in more places, in some cases changing the offset for dg-warning or dg-error directives. Changing the line numbers for dg-warning/dg-error adds further manual steps to comparing testresults and as these are generic tests I wanted to minimize the effect on the testresults for other targets.
