It is harmless all right. The actual problem is interaction between
LD_RUN_PATH encoded in executable and LD_LIBRARY_PATH. I.e. when two
libraries exist, which one is used. It may result in obscure test

The only proper workaround is to recompile zsh with different LD_RUN_PATH
value. Or use libtool - I guess, it is quite usable now. If it supports
Cygwin (there were issues) then it supports at least the same systems as
zsh internal tweaks.
