The warning plugin doesn't report linking errors when using Visual C++ 6.0
toolchain. Others errors are well notified.

The compilation is launched from a Windows Batch File by this call:
"C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\MsDev"
MyProject.dsw /REBUILD /MAKE "MyProject - Win32 Release"

The result is :

...
MainApp.cpp
Linking...
SynchronisationHeure.obj : error LNK2001: unresolved external symbol "public:
class IPosteCentral * __thiscall
CModuleBorneEtats::GetInterfacePosteCentral(void)"
(?GetInterfacePosteCentral@CModuleBorneEtats@@QAEPAVIPosteCentral@@XZ)
Release\Navineo.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

The LNK1120 error is not visible from Hudson (the others compilation error are
reported).
Feel free to ask form more details is needed.
