I described that in my report.  Let me repeat:

Manuel suggests to fix that differently, but his change will cause
Gawk fail to find extensions installed in the usual place, and I don't
know what that could break.

My proposal above, if you don't like doing it on all platforms, could
be modified to do that only on Windows, by having configure select one
of two possible commands when it produces test/Makefile from
test/Makefile.in.
