[omniORB] compiler warnings?

[Dan Kegel]

Building omniorb3.0.4 on Red Hat 7.2 I get the following warnings:

make[3]: Entering directory `/home/dank/omni/src/tool/omniidl/cxx'

                                                   ^--- expecting )

Seems like someone's grammar isn't expecting that trailing L in
a numerical constant...

../../../../bin/i586_linux_2.0_glibc2.1/omkdepend: warning:  (from idlc.cc) /usr/include/bits/stdio_lim.h: 20: # error "Never include <bits/stdio_lim.h>

I assume these are spurious; my system does indeed have Python 1.5.2 
(which comes standard with red hat 7.2)

Nevertheless, it'd be nice to be rid of them.

There are also several of the sort

That non-virtual destructor one sounds bad.  Haven't looked at it, though.

I'm compiling using 

PLAT=i586_linux_2.0_glibc2.1
OPTS="platform=$PLAT PYTHON=`which python`"
rm -rf omni
tar -xzvf omniORB_304.tar.gz
cd omni/src
make export $OPTS
LD_PRELOAD_PATH=`cd ../lib/$PLAT; pwd`
export LD_PRELOAD_PATH
cd examples/echo
make all $OPTS
