While examining build log of 18.104.22.1682, I noticed the following:
make: Entering directory
In file included from ../../../config/cf/Imake.tmpl:2175,
Imakefile:40: warning: "XF86Server" is not defined
Imakefile:45: warning: "XF86Server" is not defined
XF86Server was recently renamed to XorgServer in the tree. This looks like
a possible glitch caused by that. Probably a simple fix.
This was occurring in two different Imakefiles.
Fixed in both.
