If we start with this we have to go the whole way:

$ CFLAGS="-Wall -Wpointer-arith -Wcast-align -Wmissing-prototypes 
-Wmissing-declarations -Werror -Wstrict-prototypes -Wnested-externs" 
./autogen.sh 

...
checking whether the C compiler (gcc -Wall -Wpointer-arith -Wcast-align 
-Wmissing-prototypes -Wmissing-declarations -Werror -Wstrict-prototypes 
-Wnested-externs ) works... no
configure: error: installation or configuration problem: C compiler cannot 
create executables.
...


config.log says:
...
cc1: warnings being treated as errors
configure:1271: warning: return type defaults to `int'
configure:1271: warning: function declaration isn't a prototype
configure: failed program was:

#line 1269 "configure"
#include "confdefs.h"

main(){return(0);}

We don't want to fix all of this IMHO. And freeciv compiles without
errors with the big CFLAGS setting from above.
