So this is a  problem with libiostream from gcc 2.91 and is fixed in
later versions, e.g. 2.95.


I've tested this and it works:

add #undef bool immediately before the #include <iostream.h> in
PerlExceptionHandler.cpp

and it will compile. Also, I'm just about to release Xerces.pm 1.5.3,
you can upgrade to that if you wish, as it will have the fix (plus a
lot more functionality than 1.5.0 ...)

adjo!
jas.
