Thanks Tomas. Any chance the old version of the error message could be
restored? It would definitely be more helpful than the current one.
It's confusing to get an error and be told to use --with-pcre1 when
you're already using it.
The message now gives the required version and UTF-8 support
requirement, so one does not have to look that one line up.
Thanks to Brian Ripley,

Using --with-pcre1 to configure the latest R 4.0 (revision 77988) on
an Ubuntu 14.04.5 LTS system gives me the following error:

Maybe the real problem is that the PCRE version on this OS is 8.31?
Yes, R requires PCRE version at least 8.32 as documented in R-Admin,
and this is since September 2019.
The error message is not particularly helpful.
An earlier version of the message gave the requirement explicitly,
when people would have been more likely to have that old versions of
PCRE1.
The few who still have it now need to see also the output line above
to get the requirement and/or look into the manual.
R 4.0 is still keeping support for PCRE1 (>=8.32), but PCRE2 should
be used whenever possible.
Best,
Tomas
