Hi The file once.cpp from the repository (state yesterday) does not compile under VC7 with unicode strings (TCHAR = wchar_t).
The following patch helps: line 125: CreateMutex -> CreateMutexA There are propably other places with the same problem not compiled with my PP settings. Martin _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
