Maximum number of user variables

[Neculai Macarie]

Hi!

What is the maximum number of user variables that I can have in MySQL ? (I
need to transfer a application from one server to another and I need to
rebuild the links between tables with new id's on the new server (I'm using
auto_increment extensively), and I have a solution that involves many user
variables, around 30 000 in a single connection).
