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.ina1;

import tango.stdc.stdio;

void main()
{
    int alder;
    printf("Hvor gammel er du?\n");
    scanf("%d", &alder);
    printf("om 10 år er du %d\n", alder + 10);
}
