If you’re running a 10.90 cross-compiled by 10.1.10, you should do a native compilation from 10.90 to 10.90. Otherwise gc-renamed-object? won’t be open-coded, which could affect performance.

Thanks for the idea.  I'm doing that now on all three of my systems.

It went perfectly on my Mac and fine on my Linux laptop after I made a link from /usr/local/bin/mit-scheme-x86-64 to /usr/local/bin/mit-scheme-x86-64-10.90, but consistently fails on my Linux instance at Linode, even after I made the link in /usr/local/bin/ and an analogous link in /usr/local/lib/.  I made the links after initial failures under the theory that the build was using the binary 10.1.10 distribution instead of the new 10.90 build.

The error I get is:

;Unable to find file "edwin.bld" because: File does not exist.

This happens even from maintainer-clean.  All systems at c87066ff.
