Description John Covici 2019-11-21 05:50:29 UTC
xorg-xserver fails to compiles because the linker is lookingfor an external isastream component.

Comment 3 John Covici 2019-11-21 06:02:04 UTC
I know this worked under glibc 29.x.  I found isastream in its libc.a, but in glibc 30-r2 its not there.

patch for 1.20.5

The other patch would only apply against -9999. This one will apply against 1.20.5.
