[syslog-ng] "MSG_DONTWAIT undeclared"-error during compiling libol-0.3.17 on HP-UX 11.00/11.11

[Tob_Sch at gmx.de]

Hi,

compiling libol-0.3.16 (and syslog-ng-1.6.8) on HP-UX 11.00/11.11 worked
without any problems.
Today, I tried to compile libol-0.3.17 (and syslog-ng-1.6.9).

I got following errors during 'make':

Making all in src
        make  all-am
        source='io.c' object='io.lo' libtool=yes \
        depfile='.deps/io.Plo' tmpdepfile='.deps/io.TPlo' \

It seems, that there is no MSG_DONTWAIT variable defined in the socket.h
file on HP-UX like for example on SUSE 10.0.
It seems, that the reference to MSG_DONTWAIT came new with libol-0.3.17.
