Changed the handling of variadic intrinsics a bit. Removed the -fp80 option and made real be 80bit floats on X86, this is what the D spec really says it should be and fixes a bunch of issues. Changed the handling of parameter attributes to a bit more generalized approach. Added sext/zext attributes for byte/short/ubyte/ushort parameters, fixes #60 . Parameter attribs now properly set for intrinsic calls if necessary. Made the tango.math.Math patch less intrusive. Fixed/added some mini tests.

module tangotests.files1;

//import tango.io.Stdout;
import tango.io.File;

void main()
{
    auto file = new File("files1.output");
    char[] str = "hello world from files1 test\n";
    void[] data = cast(void[])str;
    file.write(str);
}
