因為 pmore.c 有使用到 strlcpy() 這個 *BSD 才有的函式，所以 Linux 使用者

使用 pmore.c 前要先做以下動作後。即可安心使用 pmore.c

(其實是我不知道怎麼樣讓 linux 的函式庫可以有 strlcpy...所以只好偷雞一下)


> 修改 src/lib/Makefile

SRC =   \
    str_ncpy.c str_passwd.c str_stamp.c str_str.c str_sub.c str_tail.c \
-    str_time.c str_trim.c str_ttl.c \
+    str_time.c str_trim.c str_ttl.c strlcat.c strlcpy.c \

OBJ =   \
    str_ncpy.o str_passwd.o str_stamp.o str_str.o str_sub.o str_tail.o \
-    str_time.o str_trim.o str_ttl.o \
+    str_time.o str_trim.o str_ttl.o strlcat.o strlcpy.o \

------------------------------------------------------------------------------

然後將以下兩個檔案儲存在 src/lib 下，檔名就照函式名稱儲存即可

                (複製虛線內的文字，不包含虛線)
