missing ccosh probably is a deficiency of libc/libm on your system.
Can you compile/link
#include <math.h>
#include <complex.h>
int main() { double complex x=ccosh(1.); }
on your system, and what extra libs does it need?
On my system, complex cosh is the cosh function, overloaded to accept
complex arguments. I don't have complex.h for C++ - rather I would use
#include <cmath>
#include <complex>
I had a similar problem with sage-main/sage/symbolic/pynac_cc.h, which
was looking for functions like logl. I had to change logl to log
overloaded to work with long double (just like this file does for
__CYGWIN__).
This is a definitely C++ construction, not C.
My system does have complex.h (which I think is the C99 version of C).
The only non-trivial functions it has is csqrt.
(I found this out by grepping the include directories.)
