grep shows this:

include/ncurses_mingw.h:68:extern NCURSES_EXPORT(int)  _nc_mingw_tcsetattr(
include/nc_termios.h:144:#define tcsetattr(fd, opt, arg) 
_nc_mingw_tcsetattr(fd, opt, arg)
ncurses/win32con/win_driver.c:2008:_nc_mingw_tcsetattr(

and the scripts which I use for building test-packages are in the source
tree also.  You probably overlooked

    --enable-term-driver
        Enable experimental terminal-driver.  This is currently used for the
        MinGW port, by providing a way to substitute the low-level terminfo
        library with different terminal drivers.
