Can't build git HEAD

[Raymond Toy]

I'm trying to build texinfo with git HEAD and I'm getting this error 
message:

|setlocale_null.c: In function 'setlocale_null_r': 
setlocale_null.c:179:10: error: implicit declaration of function 
'setlocale_null_r_with_lock'; did you mean 'setlocale_null_r_unlocked'? 
[-Wimplicit-function-declaration] 179 | return 
setlocale_null_r_with_lock (category, buf, bufsize); | 
^~~~~~~~~~~~~~~~~~~~~~~~~~ | setlocale_null_r_unlocked |

Didn't have any problem a month or so ago. I use a simple |configure 
--prefix=<path> CFLAGS=-g|.
