Perhaps we can adjust the code above so that MSYS doesn't
set as_test_x to 'test -x', but sets it to something else (since
'test -x' doesn't do the desired thing on your system).
What can you suggest as a substitute for 'test -x /' on MSYS?
We need a substitute that will behave differently on MSYS, but
will behave the same on ordinary systems where the above code works
fine. We would like a test that is short and efficient and doesn't
require the use of a compiler, since this code has to be run in
environments where there may not be a compiler.
For example, will this test work? If not, why not?
test -x / && { { test -x /bin/sh && test ! -f /bin/sh.exe; } || test ! -f /bin/sh; }
