Dear Rene,

Thank you for releasing the new version.

Then I got the new version using CVS.
However a compiling error occurred during make.

Compiling XrdNet.cc
g++ -c -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_REENTRANT -D_GNU_SOURCE -Wall -D__macos__ -O3 -undefined dynamic_lookup -multiply_defined suppress -DXrdDEBUG=0 -I. -I.. XrdNet.cc -o ../../obj/XrdNet.o
XrdNet.cc: In member function `int XrdNet::Accept(XrdNetPeer&, int, int)':
XrdNet.cc:82: error: `POLLRDNORM' undeclared (first use this function) XrdNet.cc:82: error: (Each undeclared identifier is reported only once for each

    function it appears in.)
XrdNet.cc:82: error: `POLLRDBAND' undeclared (first use this function)

make[5]: *** [../../obj/XrdNet.o] Error 1
make[4]: *** [Darwinall] Error 2
make[3]: *** [all] Error 2
make[2]: *** [XrdNet] Error 2
make[1]: *** [all] Error 2

make: *** [xrootd/src/xrootd/lib/libXrdSec.so] Error 2

I just typed,

% cd /usr/local/root
% ./configure macosx
% make

on Mac OS X 10.3.9.

The same version was compiled successfully on RH 7.3 with gcc 2.96. What is the reason of this error?
