[Bug-apl] SVN 839 doesn't compile


From: David B. Lamkins
Subject: [Bug-apl] SVN 839 doesn't compile
Date: Sun, 8 Jan 2017 18:11:28 -0800
User-agent: Mutt/1.7.1 (2016-10-04)

GNU APL SVN 839 does not compile. Tested with gcc 6.3.1 and clang 3.8.0 using 
./configure; make clean all .

Here are the compilation errors. I can post the entire make transcript if it'd 
help.
