Thanks for looking into this, and for addressing the potential issues so
promptly.

+1  having sources handy is good!

Excellent!

Considering that a script is used to generate it, to the point of adding
some of the comments in the output, it might be a good idea to include
it too, especially considering that scripts that control compilation are
part of the complete corresponding source code under the GNU GPL.


IMHO, a link to help users locate the assembler, as comments in the
script, would be welcome, though not mandatory IIUC.  Even though such
links tend to rot over time, they at least offer encouragement to start
or carry on a search ;-)


Thanks again,
