+descr
+ Our cabs and cabsf have a different argument format on some architectures
+ and for that we have created in libm/compat_cabs{,f}.c. The standard
+ versions in libc are __c99_cabs{,f,l} and there are __RENAME()'s in
+ <complex.h>. G++ uses __builtin_cabs{,f,l} to implement those and they
+ translate by default to cabs{,f,l} which gets defined to cabs{,f} (the
+ wrong function) and an undefined cabsl. I've changed <complex> to use
+ the __c99_cabs{,f,l} directly. Using the __builtin_cabs{,f,l} in gcc is
+ still broken.
