the  reason  is simple. bash starts only files that have permission to
execute. you can check file permissions by typing

% ls -la test.sh

you're  running  w98,  and thus have no ntsec features (ntsec emulates
unix  permissions  by native ones). when running without ntsec, cygwin
does  a  little  trick to determine which files should have executable
bit  in their permissions -- it set this bit only for files with .exe,
.cmd and .bat extensions and those which starts with magic symbols #!

note that if you try to start your script like that

% bash -c test.sh

it will work in all 3 cases, since for '-c' parameter bash won't check
permissions
