Hello,

I'm getting a build failure on the armv7hl arch
and the i686 arch, which do not make much sense.

The build is [1] and only those arche are  complaining about an sprintf() 
statement.
The rest of the arches are fine with the statment... %99.9 of the arches
that are used today... I didn't even realize i686 was still supported!

The is the failure:
conffile.c: In function 'conf_init_dir':
conffile.c:707:22: error: '%s' directive writing between 6 and 2147483645 bytes 
into a region of size between 4095 and 4096 [-Werror=format-overflow=]
  707 |   sprintf(fname, "%s/%s", dname, d->d_name);
      |                      ^~
In file included from /usr/include/stdio.h:866,
                 from conffile.c:45:
/usr/include/bits/stdio2.h:38:10: note: '__sprintf_chk' output 8 or more bytes 
(assuming 2147483648) into a destination of size 4097
   38 |   return __builtin___sprintf_chk (__s, __USE_FORTIFY_LEVEL - 1,
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   39 |       __bos (__s), __fmt, __va_arg_pack ());
      |       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So I change the sprintf() to an snprintf() [2] guaranteeing no
overflow and I got the same failure. So it is something esoteric 
about those arches... that I'm missing... 

Anybody have clue as to what is going on??

tia,

steved.
