Submitted By: Alexander E. Patrakov
Date: 2006-02-10
Initial Package Version: 1.20.1
Upstream Status: Dead
Origin: Alexander E. Patrakov
Description: Fixes lockups when signals arrive.
Details: the return value of -1 from select() that propagates into flag means
that it was interrupted by a signal. In this case, at least with glibc
from trunk (2.3.90), the return value from FD_ISSET is undefined. Thus,
GET(win) can be called when there's no actual input. This results in the
lockup until a key is pressed.
