Hi Sebastian, > No, they are also searched before system includes for #include <blah.h>: Appears to be a difference in behavior for C and C++ code. The gcc toolchain driver has the behavior you indicated using test.c; but the g++ toolchain driver has the behavior I mentioned using test.cpp (given your example situation). I was testing against C++, since that's what I normally use. Mea culpa. Sorry for any confusion. --Eljay
