building 21.2 on sparc-sun-solaris2.7, conflicting types for memmove

[Matthew Wilkins <mcw@cs.ubc.ca>]

hi,

i am trying to build emacs 21.2 on sparc-sun-solaris2.7 and get
problems with both string.h and strings.h getting included.  

here are some details (i'll give you more if necessary)

to pick up my xpm, jpeg etc libraries i do:
   setenv LDFLAGS "-L/cs/local/lib -R/cs/local/lib" 
then:
   ../configure --prefix=/cs/local/generic/lib/pkg/emacs-21.2
   --exec-prefix=/cs/local/lib/pkg/emacs-21.2
   --x-includes=/usr/openwin/include --x-libraries=/usr/openwin/lib
   --with-xpm --with-jpeg --with-tiff --with-png
the tail end of the configure gives me:
   Configured for `sparc-sun-solaris2.7'.
   
     Where should the build process find the source code?    /cs/local/src/gnu/emacs/emacs-21.2
     What operating system and machine description files should Emacs use?
           `s/sol2-5.h' and `m/sparc.h'
     What compiler should emacs be built with?               gcc  -g -O2 
     Should Emacs use the GNU version of malloc?             yes
     Should Emacs use a relocating allocator for buffers?    yes
     Should Emacs use mmap(2) for buffer allocation?         no
     What window system should Emacs use?                    x11
     What toolkit should Emacs use?                          LUCID
     Where do we find X Windows header files?                /usr/openwin/include
     Where do we find X Windows libraries?                   /usr/openwin/lib
     Does Emacs use -lXaw3d?                                 no
     Does Emacs use -lXpm?                                   yes
     Does Emacs use -ljpeg?                                  yes
     Does Emacs use -ltiff?                                  yes
     Does Emacs use -lungif?                                 no
     Does Emacs use -lpng?                                   yes
     Does Emacs use X toolkit scroll bars?                   no
   
now i build:
   gmake

the error is:
   gmake[2]: Entering directory `/cs/local/src/gnu/emacs/emacs-21.2/obj-SunOS-5.7-sparc/lwlib'
   gcc -c   -I/usr/openwin/include  -I/usr/dt/include    -g -O2
                     -DEMACS_BITMAP_FILES -DHAVE_CONFIG_H -Demacs -I. -I../src

                     /cs/local/src/gnu/emacs/emacs-21.2/lwlib/xlwmenu.c

   /usr/include/strings.h:26: warning: conflicting types for built-in function `memset'
   gmake[2]: *** [xlwmenu.o] Error 1

any help would be much appreciated

thx!
