Problem report #86

[Dan Nicolaescu]

This appeared around June 12th. 
The warning seems correct to me. Does anybody know what is the right
way to fix this?

Description: Conditional "sec >= 0"

that
6489       it does the redisplay.
6490       
6491          It's also much like Fsit_for, except that it can be used
for
6492       waiting for input as well.  */
