So, whoever is responsible for this, please step forward :) I'll test
the patch when I get home, but I have no knowledge of gcc's internals to
make a thorough check. The message gcc output, saying that -iquote
should be used instead of -I- is just plain wrong. Seeing that 4.5.0
release is just around the corner, is it feasible to have this patch
committed into 4.5 branch?
