Fix this by converting to portable getcwd(3) function. This patch fixes the following error: ---8<--- HOSTCC tools/kwbimage.o tools/kwbimage.c:399:16: warning: implicit declaration of function 'get_current_dir_name' is invalid in C99 [-Wimplicit-function-declaration] char *cwd = get_current_dir_name(); ^ tools/kwbimage.c:399:10: warning: incompatible integer to pointer conversion initializing 'char *' with an expression of type 'int' [-Wint-conversion] char *cwd = get_current_dir_name(); ^ ~~~~~~~~~~~~~~~~~~~~~~ 2 warnings generated. ...
