file name letters

Dear GHC users and developers, there has occured a curious case with file name letters. One user has built the docon library application (in Haskell) on MacOS X 10.4 + ghc-6.6.1. And making the test program has failed due to the presence of the file linalg.hs in the directory of the testing modules for DoCon. This file is not needed for this docon release, it is a reserve. I set its name in the lower case letters in order for GHC to ignore it. I test DoCon only in Linux, and have not access to MacOS. Thanks to Christian Maeder , he noticed that MacOS ignores the letter case in the file names! When the commands cd demotest ghc ... --make Main run on MacOS, ghc suddenly touches the file linalg.hs -- for some reason (and there also exists LinAlg in the library built). All right, I shall readily fix this `bug'. But out of curiosity, who's bug is this: of GHC, DoCon, or MacOS ? Is the file name letters a matter of Haskell-98 ? Do the GHC docs mention the question of the letter case in the file names? Regards, ----------------- Serge Mechveliani mechvel@botik.ru
