[Bug-gsl] missing "long_double" implementation for complex math

[Johannes Rauh]

Hello, 
 
I am using version 1.4 of GSL. When I recently tried to increase the accuracy 
of my 
program by changing all complex variables from simple gsl_complex to 
gsl_complex_long_double, I noticed that there is indeed a type called 
gsl_complex_long_double, but on the other hand none of the functions from 
gsl_complex_math.h can work with this type (for example there is no function 
like 
gsl_complex_long_double_add_real). The macros (e.g. GSL_REAL, GSL_IM), however, 
work 
well. 
Another thing I noticed ist, that it is currently not possible to use the gsl 
routines 
for eigenvalue calculations with long double precision. 
Regards,
