I believe you're missing the point. Try
../test.bat "hello world"
and you'll get the error.
I've come across this when writing a pure Windows loader for another
program. The above is actually an idiosyncrasy of the way spawn() works
in Cygwin (and, incidentally, in Windows' own MSVCRT) -- it calls
CreateProcess, which expects all arguments combined into one command
string (which, in turn, is later parsed for separate arguments - yes,
retarded, I know). The fact is that, if any argument contains spaces, it
has to be quoted before CreateProcess() is invoked. Cygwin apparently
doesn't do this properly to the first argument, so the above breaks. See
spawn_guts() in winsup/cygwin/spawn.cc (warning: a 590!-line function).
You get the same "odd evaluation behavior" when doing
echo "Hello World" | ./test.bat
(in any directory).
