[omniORB] omniORB 4.0.3 exception handling problems on Win2k

[Andrew Novikov]

We are using omniORB 4.0.3 on Linux (SuSE 9.0 Pro and FC 1) and Windows
2000. Strange things happen when throwing and catching exceptions that
contain wide-character strings on Windows. When a server throws such an
exception it sometimes turns into unknown exception. To be more
specific, when trying to execute the attached example (it is a modified
version of the 'echo' example) the client in the example catches only
first 7 out of 10 exceptions. The rest turn into "unknown user
exception".
The example always works fine on Linux and it works on Windows when it
utilizes narrow strings.

# Usage:
#   nmake /f dir.mak [<build option>]
#
#  <build option>:
#      all       - build all executables
#      clean     - delete all executables and obj files
#      veryclean - clean plus delete all stub files generated by omniidl
#        
#
# Pre-requisite:
#
# Make sure that you have environment variable LIB and INCLUDE setup for
# using Developer studio from the command line. Usually, this is accomplished
# by source the vcvars32.bat file.
#

# Where is the top of this distribution. All executable, library and include
# directories are relative to this variable.
#
TOP = C:\omniORB4

# omniDynamic403_rt.lib is the runtime DLL to support the CORBA dynamic
# interfaces, such as Anys, typecodes, DSI and DII. In these examples, the
# runtime library is not required as none of these features are used.
# However, a bug in MSVC++ causes it to generate a bunch of references
# to functions in omniDynamic403_rt.lib when compiling the stubs.
# So now we link the dynamic library as well.
# An alternative is to replace the dynamic library with the much smaller 
# library msvcstub.lib. The smaller library contains nothing but stubs
# for the required functions. This is enough when non of the dynamic
# interfaces are used. We use the small library here. If you prefer
# to link with the dynamic library, swap the comment on the next 2
# lines.
