These self-tests appears to invoke the external command 'tr' which doesn't work well under Windows, or does it?
Quoting http://autobuild.josefsson.org/gnulib/log-200908200817225767000.txt ./test-pipe-filter-gi1.exe: tr subprocess failed: No such file or directory FAIL: test-pipe-filter-gi1.sh ./test-pipe-filter-ii1.exe: tr subprocess failed: No such file or directory FAIL: test-pipe-filter-ii1.sh It doesn't seem like the 'tr' tool is essential here, so maybe it could execute a binary that is built by the self-test itself instead? Or some other expression that is more likely to work cross-platform. FWIW, there are other failures too: test-pipe-filter-gi2-main.c:132: assertion failed FAIL: test-pipe-filter-gi2.sh FAIL: test-pipe-filter-ii2.sh test-pipe.c:79: assertion failed test-pipe.sh: iteration 4 failed test-pipe.c:79: assertion failed test-pipe.sh: iteration 5 failed test-pipe.c:79: assertion failed test-pipe.sh: iteration 6 failed test-pipe.c:79: assertion failed test-pipe.sh: iteration 7 failed FAIL: test-pipe.sh /Simon
