libstdc++ headers and system headers
Sun Feb 18 06:32:00 GMT 2001

<<Now, if the only effect of using -I for system headers is, say, you don't
get the pragma that disables warnings, that's probably OK.  But if more
severe breakage occurs, it will probably be seen as a bug (sorry Robert,
I used that word again!).

Well actually I would agree with the word bug here if I understand things
correctly :-) I can't see anything in the definition of -I which would
suggest that it could not be used for system header directories.
