The problem might be that when you are in the properties dialog you
are working with a copy of the original project settings. Only when
you press 'Apply' or 'Ok' these working copy settings are transfered
to the actual '.cproject' project settings. So using

  IOption MlibOpt = ManagedBuildManager.getProjectType("stxp.target.sx.w32.exe").getConfiguration("...").getTool("...").getOptionBySuperClassId("...");

will get you the original project option, not the actual working
copy. To get the latter I think you should use the 'IBuildObject
configuration' parameter passed to 'isOptionEnabled()'. From that
value you can get the IConfiguration value which in turn can be used
to get the linker tool, and using ITool.getOptions() to get
the dynamic options (the ones with the random number, if changed).
