Subject: common/pathfind: A more portable DPRINTF()
X-Git-Tag: v4.4.1~48
X-Git-Url: http://git.pond.sub.org/?p=empserver;a=commitdiff_plain;h=a0d1f63729c4a867717bb48d7a9e45348502ddbf

common/pathfind: A more portable DPRINTF()

C99 requires at least one argument for the "..." in a variadic macro.
GCC and Clang don't care, but warn with -pedantic.  Solaris cc warns.

The warning is easy to avoid, so do it.
