We seem to have bugs with carg, cimag, creal, and fabs: They seem to handle real arguments wrong according to the Dinkumware folks. Looking at the implementation, I do not understand what's broken with fabs, but with carg, cimag and creal we only accept complex arguments. Here's a patch to fix the c* functions. Ok to commit?
