That is

# ia64-cygnus-linux-gcc -v -S x.c
#include "..." search starts here:
#include <...> search starts here:
 /usr/ia64-cygnus-linux/lib/gcc-lib/ia64-cygnus-linux/2.9-ia64-000216-final/include

It is not a problem if you use newlibc. All the C library files are
within your source tree. But I don't use newlib. My C library stuff
is under /usr/ia64-cygnus-linux/lib/gcc-lib/ia64-cygnus-linux. If
I don't create

/usr/ia64-cygnus-linux/lib/gcc-lib/ia64-cygnus-linux/2.9-ia64-000216-final

gcc won't find my C library header files via

/usr/ia64-cygnus-linux/lib/gcc-lib/ia64-cygnus-linux/2.9-ia64-000216-final/../../../../ia64-cygnus-linux/include


Yes, I have another patch to deal with .o, .a and .so files.

BTW, it was not a problem until gcc switched from

/usr/ia64-cygnus-linux/ia64-cygnus-linux/include

to

/usr/ia64-cygnus-linux/lib/gcc-lib/ia64-cygnus-linux/2.9-ia64-000216-final/../../../../ia64-cygnus-linux/include
