need help to install emacs

[Xiaoxia Dong]

I was trying to install emacs-21.2 on Sun Sparc machine. I got the 
following errors when I tried to compile the src/lwlib code.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------
gcc -c       -g -O2  -DEMACS_BITMAP_FILES -DHAVE_CONFIG_H -Demacs -I. 
-I../src -I/usr/local/src/emacs-21.2/lwlib 
-I/usr/local/src/emacs-21.2/lwlib/../src xlwmenu.c
In file included from /usr/include/X11/Xos.h:81,
                 from xlwmenu.c:32:
/usr/include/strings.h:25: conflicting types for `memmove'
/usr/include/iso/string_iso.h:62: previous declaration of `memmove'
/usr/include/strings.h:26: parse error before `0'
/usr/include/strings.h:26: warning: conflicting types for built-in function

Thank you very much for your time and help.
