visual c++ - greta compile error in VES2008 -

i compiled greta against ves2008, reports

error c2332: 'class' : missing tag name                                            error c3306: 'regex::detail::<unnamed-tag>': unnamed class template not allowed error c2143: syntax error : missing ';' before '__builtin_alignof'                 error c2059: syntax error : '__builtin_alignof'                                    error c2143: syntax error : missing ';' before '{'                                 error c2447: '{' : missing function header (old-style formal list?)                

relevant source code snippet:

template< typename t > class alignof {     struct helper     {         helper();         char    m_c;         t       m_t;     }; public:     enum { value = sizeof(helper)-sizeof(t) < sizeof(t) ? sizeof(helper)-sizeof(t) : sizeof(t) }; }; 

after precompiled, it

template< typename t > class __alignof {     struct helper     {         helper();         char    m_c;         t       m_t;     }; public:     enum { value = sizeof(helper)-sizeof(t) < sizeof(t) ? sizeof(helper)-sizeof(t) : sizeof(t) }; }; 

i have not found answers after googling. caused , how resolve it? t.i.a

although alignof not seem reserved word in vs2008, it's similar _alignof may confusing issue.

try changing name of class different.
