    Drop need for constant I in ctf test
    
    Though I is supposed to be a constant expression, this is not the case
    on vxworks, but this is not what this debug information format test is
    testing for, so use real constants to initialize complex variables.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/debug/ctf/ctf-complex-1.c: Do not test whether I is
            usable in initializers.
