To clarify this again: *no* features of C99 were used. The C99 specs were
only used as a guideline to what behavior we want of complex math
functions, and I wrote tests for this, and marked failing ones as skipped.
However, it turned out that different tests fail on different platforms,
which means that the inf/nan handling of our complex-valued functions is
effectively undefined. Eventually, most of the tests had to be marked as
skipped, and so it made more sense to remove them altogether.
