+Subject: [PATCH] clear LC_ALL when setting LC_TIME in rpn2 test
+ .
+ This test was failing when LC_ALL was set to C.UTF-8 and using the
+ C.UTF-8 locale which is part of glibc 2.35, which differs in a very
+ minor way to that that has been used by Debian/Ubuntu for years.
+ The tests sets LC_TIME to C, presumably to try to isolate itself
+ from such things, but that does not have any effect if LC_ALL is
+ set in the build environment.
