setenv/unsetenv do not exist on Windows, so the bug-repro runner failed to
COMPILE there -- this is the 'runner did not execute' failure on the
repro-windows CI job and the local Windows board alike. The compat layer's
cbm_setenv/cbm_unsetenv (already included via repro_harness.h) are the repo
idiom; test_pipeline.c uses them for the same variable.
