Think I know what the problem is now. The following files are not 
installed by default now in $prefix/include/g++:
    
    libio.h
    libioP.h
    iostreamP.h
    iostdio.h
    iolibio.h
    floatio.h

I had these files leftover from Sept 24 snapshot, and weren't overwritten
during subsequent snapshot installs. Once I installed these by hand from
current egcs/libio, my simple testcase worked as expected. The reason
that the libio testsuite worked is because it uses -nostdinc++ and then
explicitly includes the libio source in the include path, hence not
looking at the bad copy in the installation tree.
