[svn-r1114] Purpose:

Bug fix

Problem:
    On Solaris2.5, once the library has been compilied with any type of
    optimization, a bus error comes up in the "dtypes" test.

Solution:
    The problem appears to be in the compilers' version of memcpy() that
    is used when optimized.  Apparently, the same optimization problem
    is not associated with the similar function memmove().  So, as a
    solution to this problem, memmove() is substituted in for memcpy().

Platform tested:
    Solaris2.5
