------- Comment #15 from chris dot litchfield at gmail dot com 2010-05-18 19:48 ------- This is still a huge issue. We would wish to inhibit use of the CURRENT Working directory to find include files. Basically FORCE every time a new include file is found with #include to start AGAIN from the begining of the Include Path system. using -iquote will simply cause the same problem where an include file that includes another include file will include that sub-include file even if you can pulled it away in a previous include path.
Make files with VPATH or put Development paths first in lists are totally hosed by removing the -I- functionality. This is NOT an enhancement but a Priority 2 bug which there is NO WORKAROUND provided by removing a feature. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19541
