When I tried to install emacs 21.2 on my Sun Blade 100 station running Solaris 
2.8, I encountered the following problem:

configure --prefix=/opt/local
gmake

.....

gmake[2]: Entering directory `/opt/temp/emacs-21.2/lwlib'

/usr/include/iso/string_iso.h:62: previous declaration of `memmove'

gmake: *** [src] Error 2

The preprocessed file xlwmenu.i.bz2 is attached. It appears that bcopy is 
#define'd to memmove before the prototype of bcopy is read from 
/usr/include/strings.h. This leads to the conflicting types error.
