Here's a very simple example:

    #include <stl.h>
    typedef int *intP;
    typedef  list<intP> intlist;
    fubar()
    {
       intlist alist;
       remove(alist.begin(), alist.end(), NULL);
    }

The interesting thing is that if one were to replace NULL above with
an (intP)0, everything is okay. No errors were reported. 

The cpp output does not seem to transform any lines in there except
making NULL into __null. 

I'm not a c++ language lawyer, but I thought the use of NULL was
okay. Even if it's not, egcs shouldn't generate a bad id for asm to
choke on, right?

I'm sending you the output of egcs -E and egcs -S in a seperate
message for fear that my mailer would not let such a long message
thru...

Thanks for looking into it.

hxl
