I always test the rollup patch against the release (not knowing exactly
what you did, I can't tell what's wrong).  You need tar, gzip, uudecode
and of course patch.

EXEEXT didn't correspond to any release version of autoconf at the time 5.2
was released.

NEWS serves that purpose.

that's a rather ugly solution, btw (would be better to provide a special
function for this than to distort the meaning of tcgetattr).

what library provides ScreenRows() and ScreenCols()?
