Right now, pack/unpack
a) use memcpy, even if a native type is available
b) convert mask arguments of kind 1 and 2 to default
logical kind, which wastes cycles and memory
Case b) is actually true of all intrinsic functions with mask.

There are major failures in the lapack 3.1.1 tests with gcc 2.95.3 and in the

the routines chgeqz and zhgeqz are compiled with -O2.

Andrew, do you want to convert to sizetype or to ptrdiff_t? Does it matter?
sizetype is correct for POINTER_PLUS_EXPR. We don't have a ptrdiff_t
