Getting errors from crtdefs.h - c

Question

After a battle trying to include ncurses in my project with makefile, when i try to make .o files it gaves me this errors:

I am learning to programming in C and i couldn't found nothing related with this and others errors with ncurses saying that curses.h didn't exist(i tried this both directives ncursesw/curses.h and curses.h). I dont know if OS matter but I'm running in windows. The main code is just a test code for this compilation:
#include <ncursesw/curses.h>
#include <stdlib.h>
int main()
{
int x=10;
initscr();
raw();
printw("%d",x);
getch();
endwin();
return 0;
}

I just reinstalled MinGw Posix and didn't merge the opt folder with include folder, probably I accidentally rewrited crtdefs.h the first time i installed MinGW.
