The really annyying this is:

a) this used to work perfectly for all the borland DLL tests. It only
started to occur after some changes in export.hpp. (and maybe somewhere

b) It only occurs on some of the tests.

c) It may be particular to my machine. I've noticed that my borland test
failures on my machine don't always occur in the regression test matrix. So
it seems there are various versions of borland 5.64 out there.
