It's not: if type deduction is working correctly, then it converts from
const char* to char*, which is legal for const_cast (see 15.2.11p3).  I
realise that this is a hack BTW: however the pointed to value is never
actually written too, the const-ness is cast away only to interface with the
iostream machinary.

You could try putting a C style cast in there to see if that fixes things,
but you're likely see a lot of other errors...

Sure: see http://boost.sourceforge.net/regression-logs/

> Do you intend to make it buildable with aCC ??

If someone is prepared to supply patches - be aware however that it's an
uphill struggle - aCC seems to have more than the usual share of bugs :-(

If you're planning on trying to patch regex though, can you please look at
the latest cvs code - the code has changed a lot since the last release,

thanks,
