It builds without warnings using 'gcc -std=c89' but fails if I add

../src/subversion/libsvn_subr/errorcode.inc:6:18: warning: ISO C forbids empty 
initializer braces [-Wpedantic]
 } svn__errno[] = {
../src/subversion/libsvn_subr/errorcode.inc:6:3: error: zero or negative size 
array ‘svn__errno’
 } svn__errno[] = {

I suppose I could insert a dummy entry for zero.  The code that uses the
array will never look for zero since there is an earlier return.
