Subject: Add a few casts, fix compiler warnings on NetBSD 5
X-Git-Tag: rel-20-rc2~9
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=44926b7f9ff031c37be48b33c314e47e2f84ff9f;p=ngircd

Add a few casts, fix compiler warnings on NetBSD 5

This fixes a few warnings of this type:
  XXX.c: In function 'AAA':
  XXX.c:YY: warning: array subscription has type 'char'

Tested on NetBSD 5.0.2 with gcc 4.1.3.
