[Help-gsl] GNU Reference Manual 37.9 Examples

[bmacox]

Hello:

I tried to run Example programs for Nonlinear Least-Squares Fitting, 
http://www.gnu.org/software/gsl/manual/html_node/Example-programs-for-Nonlinear-Least_002dSquares-Fitting.html

I copied the expfit.c on the top of the page and the main program into a 
main.cpp.? But when I compiled the current file in Dev C++, I got various 
errors, such as

97 C:\Dev-Cpp\main.cpp expected `,' or `...' before '*' token 

for the line
expb_f (const gsl_vector * x, void *data, gsl_vector * f)

How do we get the example to run properly in Dev C++ 4.9.9.2?

Thx very much!!

The LM implementation in GSL is described here:
