using gretl as a dll library in mql4 programming

[yasharino]

This is a comprehensive program for time-series analysis. I want to use your source as a dll library in mql4 programming to test stationary and degree of cointegration of stock market time-series. But mql4 accepts dll importing libraries according to following code. Would you please export gretl functions in dll extension with their function description to use in mql4 programming?
Best wishes

#import "file_name"
func1 define;
func2 define;
...
funcN define;
#import
