declaration of fwide is missing

[Bernd Prager]

Hi,

Trying to compile revision 620889 with g++ (GCC) 4.2.3 on cygwin
CYGWIN_NT-5.1 1.5.25(0.156/4/2) gives me the error message:

systemerrwriter.cpp: In static member function 'static bool
log4cxx::helpers::SystemErrWriter::isWide()':
systemerrwriter.cpp:55: error: 'fwide' was not declared in this scope


Any suggestions or chance to fix it?

Thanks a lot,
-- Bernd Prager
