I've just comitted a test and a fix for this problem.

The log message, which explains the fix, is:

    Solve a problem which prevented specifying negative values. Previously,

       -a -1

    was always parsed as two separate options. Now, we check if '-a'
    requires value and '-1' is not a recognized option. In that case, we
    treat '-1' as value.

> int main (int argc, char** argv) {
> double angle;

I've cheched your example, and now it works.
