Subject: Find dbus-daemon executable next to dbus shared libaray on windows.
X-Git-Tag: dbus-1.4.18~15^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d52b86d3e774ed515039f47b2a35ec645362a97b;p=thirdparty%2Fdbus.git

Find dbus-daemon executable next to dbus shared libaray on windows.

If the dbus shared library and the daemon executable are both in a dir
that is not part of the default search path and dbus-1.dll is dynamically
loaded with LoadLibrary(), it will fail to locate and launch the daemon
without this patch.
