[omniORB] OmniOrb incompatible with Boost library

[David Bertrand]

Hi,
 
Background
MSVC7 libraries compiled with -Zc:wchar_t switch (Treat wchar_t as
Built-in Type) are incompatible with the ones compiled without. This
basically changes the compiler interpretation of wchar_t from unsigned
short to a native wchar_t.  Everything go fine until you link to unicode
functions. Since it's a global compile setting, your application cannot
mix and match libraries compiled with different setting : it will give
you link errors.
 
Boost v1.35 library uses the -Zc:wchar_t switch, and OmniOrb do not use
it.  Since MSVC8 activates the -Zc:wchar_t switch by default, I feel it
confirms Boost is right. For testing purposes, I added the switch to
current release. 
 
Here are the changes required for omniorb-4.1.2 :
 
\mk\platforms\x86_win32_vs_7.mk line 31
Enables "Treat wchar_t as Built-in Type" (-Zc:wchar_t).
 
MSVC_DLL_CXXNODEBUGFLAGS       = -MD -EHs -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_DLL_CXXLINKNODEBUGOPTIONS = -nologo -DEBUG
MSVC_DLL_CNODEBUGFLAGS         = -MD -GS -GR -Zi -nologo -Zc:wchar_t
MSVC_DLL_CLINKNODEBUGOPTIONS   = -nologo -DEBUG
#
MSVC_DLL_CXXDEBUGFLAGS         = -MDd -EHs -RTC1 -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_DLL_CXXLINKDEBUGOPTIONS   = -nologo -DEBUG
MSVC_DLL_CDEBUGFLAGS           = -MDd -RTC1 -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_DLL_CLINKDEBUGOPTIONS     = -nologo -DEBUG
#
# Or
#
# Use the following set of flags to build and use multithread static
libraries
#
MSVC_STATICLIB_CXXNODEBUGFLAGS       = -MT -EHs -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_STATICLIB_CXXLINKNODEBUGOPTIONS = -nologo -DEBUG
MSVC_STATICLIB_CNODEBUGFLAGS         = -MT -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_STATICLIB_CLINKNODEBUGOPTIONS   = -nologo -DEBUG
 
MSVC_STATICLIB_CXXDEBUGFLAGS         = -MTd -EHs -RTC1 -GS -GR -Zi
-nologo -Zc:wchar_t
MSVC_STATICLIB_CXXLINKDEBUGOPTIONS   = -nologo -DEBUG
MSVC_STATICLIB_CDEBUGFLAGS           = -MTd -RTC1 -GS -GR -Zi -nologo
-Zc:wchar_t
MSVC_STATICLIB_CLINKDEBUGOPTIONS     = -nologo -DEBUG
 
My version compiled with this change linked and ran fine.
Feel free to comment.
 
Thanks,
 
David
