Who is working on this? I commented out that piece of code, chanegd a subsequent
call to _IO_SYSSTAT yo _IO_WSYSSTAT and changed the call to _IO_DOALLOCATE in
wgenopts.c to _IO_WDO_ALLOCATE. this giot it a bit further in initialisation.

I found a problem in __basic_string<wchar_t>::__basic_string - it calls
IO_doallocbug, but it appears that the non wide entries in the JUMPTABLE are not
initialised.

I'm starting to get out of my depth here - commenting these calls out got me as
far as finilistion (_fini) but then I hit some weirdo errors in std_fstream
static destructors.

anyone got any pointer / wants my patches?

Thanks,
