Use const char* where appropriate to avoid discarding constness. Use size_t type where appropriate to avoid signedness warnings, adjust format accordingly. Add prototype to function pointer array declarations. Cast arguments to isxxxxx(): undefined outside of <-1,max(u_char)>
A couple of variables changed from int to size_t to avoid signedness warnings. Convert code to use a literal format. Cast arg to islower() to ensure safe value range of argument.
The VOIDP() replaces a complicated double cast.
This should avoid warnings about incompatible pointer types.
Actually, this was a bug of my own; NetBSD uses asprintf() and therefore avoids this particular problem. However, asprintf() isn't sufficiently standardized to use here, I suspect.

Gents, what's the status of this report? Can we please track any pending or new issues like this at bugs.ntp.org? |

Folks, I know we've made changes to the codebase since this was opened, and we've just fixed even more of these via http://bugs.ntp.org/show_bug.cgi?id=2821 Can we close this issue? |

Hi,
I finally updated my local tree and did a rebuild, and it looks a
lot better, but there's a pair of warnings about char subscripts
still:
ntpq.c: In function 'list_md_fn':
ntpq.c:3543:2: warning: array subscript has type 'char' [-Wchar-subscripts]
if( islower(*cp) )
^
ntpSnmpSubagentObject.c: In function 'ntpsnmpd_parse_string':
ntpSnmpSubagentObject.c:100:5: warning: array subscript has type 'char' [-Wchar-subscripts]
field[j++] = toupper(string[i]);
^
Regards,
- Håvard

This is a set of changes mostly pulled from the NetBSD
repository, where ntp has been tweaked to build cleanly
with the set of warning flags we enable in our build.
There are a few additions which are of my own, which
came from trying to build the code after applying these
changes.

"Patches for stricter compiler settings" of 29 Nov 2015.
