regression failure on SFCGAL

[robe]

I just started getting this error and I see it on winnie too ​https://winnie.postgis.net:444/job/PostGIS_EDB_Regress_winnie/11260/consoleFull

Not sure why it is not happening on other bots so might be mingw specific. I assume it's one of strk's SFCGAL script changes yesterday at fault.

I should add aside from windows, what winnie and I have in common that I don't think the other bots do (even the sfcgal testing ones) is that we test with the

--with-library-minor-version

configure switch. I don't think the other bots test that switch

In d781ecf2/git:

Have probin test support more than a single letter versioning

Fixes #4778
