Subject: internal.h: Use `unsigned' for nextid
X-Git-Tag: adns-1.5.2~13
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=b36d9bf08f95ef570a29a519ddc6d97bf287d919;p=adns.git

internal.h: Use `unsigned' for nextid

This is constantly incremented and needs to wrap.  In practice I don't
believe any compilers spot the UB.
