I am happy to announce the final release of the Mailman 2.1.11.

Should I worry?

When I build my 2.1.11 package for Ubuntu this morning I saw those (and others), and I did some research:

src/_koco_ksc5601.h:1493:

 static unsigned char *ksc5601_encode_page0[945] = { /* 0x00a1 - 0x0451 */
 "\xa2\xae", 0, 0, "\xa2\xb4", 0, 0, "\xa1\xd7", "\xa1\xa7",

 There is one message for each non-zero value (e.g., "\xa2\xae").

src/_koco_uhc.h:1613:

 static unsigned char *uhc_encode_page0[11170] = { /* 0xac02 - 0xd7a3 */
   "\x81\x41", "\x81\x42", 0, "\x81\x43", "\x81\x44", 0, 0, 0,

 There is one message for each non-zero value (e.g., "\xa2\xae").

src/koco_stream.h:42: warning: pointer targets in assignment differ in signedness src/koco_stream.h:43: warning: pointer targets in assignment differ in signedness srccur = s; [unsigned char = char] srcend = s + slen; [unsigned char = char + int]

 The same is true for lines 135 and 136.

And there are similar errors in a handful of other routines.

I have not yet installed my 2.1.11 package on my test machine, but my records show that I had the identical messages when I built my 2.1.9 package, which I use in production. I am not an expert in the C language and what type conversions are done. But I would not worry about these messages. I do not know if the C code can be changed to eliminate these messages.

I captured the output of my package build process using the "script" command. That output file has
