find_reg computes the cost of moving to target register too high. This kludge
adjusts the cost of moving to target register and seems to work for the
testcase:

Thanks - the most recent SVN has fewer DFP errors.
If we _really_ don't want DFP on any platform except PowerPC then we should
change ./configure for it to be prohibited. I can't see why it could not be

The testcase fails with 3.4.6, but doesn't fail with 4.0 and later
compilers. So I'd like to close this PR as WONTFIX because 3.4 was
frozen.

You need to define Base::x out of class in some translation unit, the in-class
declaration alone isn't enough, though sometimes the compiler will elide the
reference to it if its value is known (optimization).
