Our organization changed OS version and compiler (from GCC 3.2.2 to GCC =
3.2.3). As part of the move, the CM powers-that-be tightened the code =
requirements such that compiles fail on any warning. As a result, our =
code was choking on a line in null.h where the operator () function of =
class null_type was not returning a value (throws BadNullConversion as =
it should). The included patch is what we used to fix the problem in =
our little world.

This is against 1.7.26; we haven't updated yet. However I just checked =
and the patch should work against the latest code.

Anyway, here's the diff, humbly submitted...:

Ugh. Try this instead:

template <class Type> operator Type ()
{
throw BadNullConversion();
return Type();
}
