[ECB-list] save-excursion defeated by set-buffer - what does this mean?

[Berndl, K. <kla...@ca...>]

Hi,

when byte-compiling ECB with forthcoming Emacs 23.2 then i get myriads of this Warning:
save-excursion' defeated by set-buffer.

Can anybody tell me what does this mean?
And maybe how to prevent Emacs from nagging this?

Thanks a lot
Klaus
