Re: ezunits fundamental_units apparently broken in Maxima 5.49.0

Dear Maxima List Readers,

sorry, please ignore my below mail. I had a somewhat patched version of 
ezunits in my user maxima folder. it is quite a bit faster, but I never 
came to fully review it and do a PR. This version broke with the update 
to 5.49.0. I completely forgot about this - it has been a while since I 
touched it. The funny thing is that pretty much everything else in 
ezunits was still working fine - I crunched huge symbolic 
antiderivatives with it without issues. Just fundamental_units broke.

Sorry again for the noise.

Best regards,

Michael
