We use the configure script.  It shows:

checking for long double... yes
checking size of long double... 16

Yet the preprocessor shows:

../../../bin/omniidl -bcxx -Wba -p../../../../src/lib/omniORB -Wbdebug
-v -nf -P -WbF -ComniORB4 ../../../../idl/corbaidl.idl
omniidl: Importing back-end 'cxx'
omniidl: 'cxx' imported from
'../../../../src/lib/omniORB/omniidl_be/cxx/__init__.pyc'
omniidl: Preprocessing '../../../../idl/corbaidl.idl' with
'/project/aero/swdev/perf/omni407/hp11i/lib/omnicpp -lang-c++ -undef
-D__OMNIIDL__=0x2420 -DHAS_LongLong -D__OMNIIDL_CXX__
"../../../../idl/corbaidl.idl"'

We've tried to trace this problem before without any luck.  Can you
suggest where to look?

Thanks,
Craig
