My recollection is that the version immediately prior to 1.875 was
actively broken, and that versions much before that fail to cope with
the current size of our grammar.
What I see in ftp.gnu.org since 1.875 are 2.0, 2.1, 2.2, 2.3. We do not
know at this point whether the extra-semicolon bug is present in 2.0
or only 2.1 ... but I will download them and find out.
