# RNV: In the SALOME sometimes operating with STL collections is done in not fully valid way. 
#      To avoid run-time exception in Debug mode default values of the _SECURE_SCL, 
#      _SECURE_SCL_THROWS and _HAS_ITERATOR_DEBUGGING macros were redefined. It solved a problem 
#      then we used tne Microsoft Visual Studio 2008 to build SALOME on Windows platform.
#      But in the Microsoft Visual Studio 2010 these macros affect on the size of STL collection 
#      classes(in difference from the Microsoft Visual Studio 2008: in this version of MSVS size
#      of the STL collection  classes does not depend on these macros).
#      All pre-requisite products are built by MSVS 2010 in Debug mode with the default 
#      values of the metioned above macros (namely _SECURE_SCL=1, _HAS_ITERATOR_DEBUGGING=1 and
#      _SECURE_SCL_THROWS=1). So SALOME modules should be build in the same configuration.
