------- Additional Comments From dpatel at apple dot com 2004-11-19 01:21 ------- It seems -isysroot may do the task here. I see its implementation in c-opts.c, but unfortunetly 1) it is not documented in cppopts.texi and 2) driver has one bug that causes it to eat isysroot argument. I will investigate.
