They can, -fno-builtin. But that's really not solving the underlying
problem. HP changed the type of size_t and/or ptrdiff_t between hpux10
and hpux11. For a variety of reasons gcc needs to know the precise
definitions of those types. When gcc has the wrong definitions of those
types a variety of bad things happen.
It is also necessary to add some cpp predefines to make hpux11 work
correctly.
