Including the < and > in the pathname triggered a syntax error. Likely I 
misundersood the tip or I'm using a different shell.

The file has been placed at
http://www.zefox.net/~fbsd/rpi2/20260506/

After placing it there using sftp, running file on it locally reported
fbsd@www:~/public_html/rpi2/20260506 % file *
ParseDecl.o: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (FreeBSD), missing section headers at 1249720

Perhaps unsurpisingly it can't be viewed in a browser. 
It does display neatly (but unintelligibly to me) using
hexdump.

Thanks for writing, please indicate any more experiments
that come to mind.
