This bug avoided in _defs.h:
_defs.h, line 1020:
-----------
# ifndef _RWSTD_NO_STATIC_CONST_MEMBER_DEFINITION
# define _RWSTD_DEFINE_STATIC_CONST(decl) decl
# else // if defined (_RWSTD_NO_STATIC_CONST_MEMBER_DEFINITION)
// disable defintion of static const integral members
// to work around compiler bugs such as those in MSVC
// or Intel C++/Windows that cause multiple definition
// linker errors (see PR #26562 and #30260)
# define _RWSTD_DEFINE_STATIC_CONST(ignore) /* empty */
# endif // _RWSTD_NO_STATIC_CONST_MEMBER_DEFINITION
-----------
I've commented the #if !defined (_MSC_VER) || (_MSC_VER <= 1300)
and corresponding #endif lines in ios_bits.cpp, and the test shows no
any errors.
Farid.
