As mentioned elsethread this works if using bash rather than the system's sh (which is a ksh)

But there are several other failures. After some investigations and experiments I found the following tests to fail with the system
provided grep (for which I had to set GIT_TEST_CMP_USE_COPIED_CONTEXT), but succeed with GNU grep:
t3308 #14, #15, #17and #19
t3310 #10, #12, #14 and #18
t4047 #38 and #39
t4050 #2 and #3
t4116 #3, #4 and #5
t5509 #2
t7401 #18

The following fail with the system provided tar, but succeed with GNU tar:
t0024 #2
t4116 #4,
t5000 #14, #16, #20, #24, #26 and #51
t5001 #2, #6, #10 and #15

The following tests fail with the system provided sh (which is a ksh really), but succeed with bash:
t0000 #12
t0001 #20
t1450 #17 and #18
(t0204 #3 and #8 succeed in sh but fail in bash. They succeed in bash too when /usr/local/bin is in PATH first though, which would
sort the diff and tar problem too, need to investigate why)
t3006 #2 and #3

t3403 #4, #5, #8 and #9
t3404 #2 - #13, #14 - #18, #20 - #41, #44, #46 - #70
t3409 #2 - #5
t3410 #2 and #3
t3411 #2 and #3
t3412 #8, #10 - #12, #15, #17, #23, #25, -26, #28, #29, #31
t3413 #3, #5 - #10, #14, #15
and many more...

The following needs bash and /usr/local/bin first in PATH ("PATH=/usr/local/bin:$PATH make test")
t0204 #3 and #8 (or just sh, see above)
t3032 #11
t3900 #24, #25
t4201 #8
t5000 #14
t5150 #6

I though "SANE_TOOL_PATH=/usr/local/bin" plus "SHELL_PATH=/usr/local/bin/bash" would to fix the all but it does not and instead
brings up some other failures too:
t5521 #2 and #5
t5526 #2, #5, #8, #10, #12, #13, #16 - #19, #21 - #25
t5702 #3
t5800 #2, #3, #5 - #14
t9001 #66

With additionally having "PATH=/usr/local/bin:$PATH" all but one work, so there must be something wrong with SANE_TOOL_PATH?.
The single failure remaining is
t0301 #12 "helper (cache --timeout=1) times out"
I don't understand this at all, neither the -v options nor running it with bash -x helps me in understanding what the issue is.

Bye, Jojo
