G++ suggestions (no inlines)

[Michael Tiemann]

Note that I am posting this to bug-g++ instead of info-g++, since this
more a bug fix than general interest to GNU C++ users.

If you want to try Bryan's integrate.c diffs, these are better (though
still not necessarily correct). The main difference is that NOTEs
such as NOTE_INSN_LOOP_BEG should not be deleted--only line number
notes should be deleted.
