I know that it is self-explanatory but my jpeglib.h header file has 
JPEG_LIB_VERSION = 62.
No I don't have neither jpeglib.h nor libjpeg-turbo package old.

But I am going to find if there could not be a problem with emacs 
configure script.
Several times there is mentioned conftest.$ac. I am going to test it.
I think that emacs configure scripts does not work well some times.
