Don´t know how to do it most correctly so I tried to attach my
signal.h to e-mail (its copy is on pastebin.com/t2fGNhsp ). I
compared it with signal.h file I ams using for Unix and it´s a lot
different. My signal.h file for Windows comes from Gtk+ or Gtkmm
package downloaded from GTK website. Dne 9.1.2012 15:35, Kjell Ahlstedt napsal(a): I haven't got mingw installed, and I have never used it, so I'm not the best person to reply. |

* @code
* struct arithmetic_mean_accumulator

* typedef double result_type;
* template<typename T_iterator>
* result_type operator()(T_iterator first, T_iterator last) const

* struct interruptable_accumulator
