There is a bug for atan(x) and tan(x) in both the
beta 14 and beta 16 releases of Cugnys GCC.

They work OK for small arguments but for example
atan(4) is in gross error.

However the functions atanf(x) and tanf(x) works
as good substitutes.

We use #define tan tanf ..etc as a workaround
in the file math.h

Hope this will be corrected in the beta 17 release
