Okay, this is getting somewhat OT and should probably rather go to the 
cygwin list. Anyway,

ruby.bat:
bash -c "ruby.exe $(cygpath -u '%1') %2 %3 %4 %5 %6 %7 %8 %9"

test.rb:
p $0, "Succeeded!"

At the command line (cmd.exe):
G:\>ruby.bat g:\tml\src\test.rb
"/mnt/g/tml/src/test.rb"
"Succeeded!"

$(foo) is equivalent to `foo`. A matter of taste.

Anyway, the solution with modifying RUBYLIB or some other env variable 
should work too -- maybe in a wrapper of the script you're calling. In 
general, I think mixing cygwin & native win apps isn't a good idea which 
is why I would suggest to install either ruby4win or tetex4cygwin.

Cheers,
Thomas.
