With gcc 4.0.0 from today (December 9, 2004), I receive the error message
error: subscripted value is neither array nor pointer
for a piece of code that looks fine and is accepted by Intel's icc. Some
relevant lines seem to be e.g.
const char* const coords = "xyz";
for (int d=0; d<D-1; ++d) os << "i" << coords[d] << " "; os << "i" <<
coords[D-1];
which looks as if there was a problem indexing the "coords" string.
I compile with the options
$ /home/eschnett/gcc/bin/g++ -ftrapv -march=pentium4 -malign-double -g3 -c
ioascii.ii
and the screen output is
