I don't think this is legal C89 code (from vector/reim_source.c):
QUALIFIED_REAL_VIEW(gsl_vector, view)
FUNCTION(gsl_vector, real) (QUALIFIED_TYPE(gsl_vector) * v)
{
REAL_TYPE(gsl_vector) s = NULL_VECTOR;
s.data = v->data;
s.size = v->size;
s.stride = MULTIPLICITY * v->stride;
s.block = 0; /* FIXME: should be v->block, but cannot point to
block of different type */
s.owner = 0;
{
QUALIFIED_REAL_VIEW(gsl_vector,view) view = NULL_VECTOR_VIEW;
((REAL_VIEW(gsl_vector,view) *)(&view))->vector = s;
return view;
}
}
The Solaris C compiler gives:
cc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -mr -Qn -xstrconst -xO2
-xtarget=generic -c reim.c -KPIC -DPIC -o reim.o

I don't believe you can cast an lvalue.
