What do you mean it limits number of items via POP3? How many new mails you
have?
Gmail AFAIK only disables standard behavior of DELE command and instead of
deleting it acts as set in settings of Gmail account (usually marks message

i.e. is this scenario safe:

Well, like I wrote, it effects all programs that use ICS. And it is a
bit harder to find a solution that fits all in this case due to nature
of the problem.
This is how ICS loads for example SSLLEAY32.DLL:

...

It appears that this new vulnerability requires programs to adopt

Arno,
This appears to solve the issue. The project I have now compiles without
errors with this version as well.
/me is happy
I have 2 snapshots. The one I downloaded on 2009-11-18, and the one I
downloaded on 2010-05-03 (so it is snapshot from 2010-04-28 in fact which is
the last date I see in the history).
When I compile a project I have, it stops with the following error message:
