mined: built without UNIX defined.
* Remove undef NULL, EOF, getchar, putchar * Rename putchar, getchar, _putchar, _getchar to putch, getch, _putch, _getch to avoid conflict with libc functions. * Rename UP() to UP1() (for UP 1 line) to avoid conflict with UP definition in termcap.h. Rename DN1 LF1 RT1 for consistency. * Add termcap.h for prototypes for tputs and friends. * Add libterminfo references to Makefile * Add return value to _putch() to make it work as tputs expects. * Make putch() call _putch() * Remove UNIX ifdefs and all code in the !UNIX branches. closes #43 Change-Id: I0a6f7298aa8b12a74225badc88d3c236a02669ea
