$ ./test

You've fallen foul of two things. First off, is searches are only made along
$PATH. Second is a common mistake. In unix there's a command called 'test'.
This will have been executed instead, hence the behaviour you observe. EG:

$ if test -d test.exe; then echo dir; else echo file; fi

"man/info test" for details. In other words, don't name your executables
"test"! ;-)
