Fantastic! I build 2.7.0 and can confirm the macrolet issue is fixed.

However, I do have a build issue. I had to run autoconf again because I 
don’t have aclocal-1.17. Everything built fine. But then I did make 
install. When I run the installed gcl, it can’t find 
/usr/lib/gcl-2.7.0/unixport/saved_gcl. I ran “configure 
–prefix=$HOME/dev/gcl-2.7.0”. There is saved_gcl in 
$HOME/dev/gcl-2.7.0/lib/gcl-2.7.0/unixport/saved_gcl, as I would have 
expected.
