UNIX FD passing is supported by Solaris, but additional compile flags are required

If would be nice to have a patch (best would be git format-patch) with  
the required change in the build system probably configure.in. I guess 
the related line will starts with

case $host_os in
     solaris*)

for example In configure.in line 553ff there is the following code

# Add -D_POSIX_PTHREAD_SEMANTICS if on Solaris
#
case $host_os in
     solaris*)
        CFLAGS="$CFLAGS -D_POSIX_PTHREAD_SEMANTICS" ;;
esac

in which the additional define may be addable.

BTW: in line 1309 the above mentioned code is duplicated - not sure if 
this is required or not

# Add -D_POSIX_PTHREAD_SEMANTICS if on Solaris
#
case $host_os in
     solaris*)
        CFLAGS="$CFLAGS -D_POSIX_PTHREAD_SEMANTICS" ;;
esac

May be the solaris case(s) could be cleaned up a bit.
