isolatedModules fails because of path backslashes on windows

[arogg]

i get an error when using gulp typescript with isolatedmodules option on windows (ts compiler just throws an assert error, without any further details). what I did was merely trying to duplicate the gulp-typescript isolated modules test in the repository as far as possible.. it is this line that causes the problem:

return typescript.transpile(input, compilerOptions, fileName, diagnostics);

when I replace the line with:

return typescript.transpile(input, compilerOptions, fileName.replace(/\\/g,"/"), diagnostics);

everything works.

the error that occurs without the change is:

Thanks for reporting!

I see you did path.normalize to try to fix it. but that won't work. On windows that leaves the backslashes, because the method is os specific... you need to convert the backslashes to slashes, even on windows to fix the bug.

Sorry, you're correct about that. Fixed it.
