[m-users.] 22.01 beta release available

[Fabrice Nicol]

Ah. Alert definitely NOT lifted.

ROTDs and the beta release, ** on GitHub's release section ** do NOT 
have mercury_compile.c under compiler/

Packages do not have the same checksums as on the official Mercury 
Language download page.

So actually the 'mangled' package/build failures of my prior messages 
were just caused by the fact that I downloaded an incomplete package 
from GitHub then turned to the official dl page believing packages were 
identical. They are not:

Proof:

mkdir a && cd a && wget 
https://dl.mercurylang.org/rotd/mercury-srcdist-rotd-2022-01-25.tar.gz 
&& tar xzvf mercury-srcdist-rotd-2022-01-25.tar.gz && cd -

     mkdir b && cd b && wget 
https://github.com/Mercury-Language/mercury-srcdist/archive/refs/tags/rotd-2022-01-25.tar.gz 
&& tar xzvf rotd-2022-01-25.tar.gz && cd -

     diff -r a/mercury-srcdist-rotd-2022-01-25 
b/mercury-srcdist-rotd-2022-01-25 | grep mercury_compile.c

Copy-paste and run, you'll find (in a French locale ;) ):

Seulement dans a/mercury-srcdist-rotd-2022-01-25/compiler: mercury_compile.c
     Seulement dans a/mercury-srcdist-rotd-2022-01-25/compiler: 
mercury_compile.c_date

Huh. Checksums...
