+See http://gcc.gnu.org/PR22541
+
+From: Dan Kegel
+
+When building gcc-3.4.3 or gcc-4.0.[01] into a clean $PREFIX (the only two I've tried like this),
+the configure script happily copies the glibc include files from include to sys-include;
+here's the line from the log file (with $PREFIX instead of the real prefix):
+
+Copying $PREFIX/i686-unknown-linux-gnu/include to $PREFIX/i686-unknown-linux-gnu/sys-include
+
+But later, when running fixincludes, it gives the error message
+ The directory that should contain system headers does not exist:
+ $PREFIX/lib/gcc/i686-unknown-linux-gnu/3.4.3/../../../../i686-unknown-linux-gnu/sys-include
+
+Nevertheless, it continues building; the header files it installs in
+ $PREFIX/lib/gcc/i686-unknown-linux-gnu/3.4.3/include
+do not include the boilerplate that would cause it to #include_next the
+glibc headers in the system header directory.
+Thus the resulting toolchain can't compile the following program:
+#include <limits.h>
+int x = PATH_MAX;
+because its limits.h doesn't include the glibc header.
+
+That's not nice. I suspect the problem is that gcc/Makefile.in assumes that
+it can refer to $PREFIX/i686-unknown-linux-gnu with the path
+ $PREFIX/lib/../i686-unknown-linux-gnu, but
+that fails because the directory $PREFIX/lib doesn't exist during 'make all';
+it is only created later, during 'make install'. (Which makes this problem
+confusing, since one only notices the breakage well after 'make install',
+at which point the path configure complained about does exist, and has the
+right stuff in it.)
+
+A possible fix is to replace the line in gcc/Makefile.in that says
+ SYSTEM_HEADER_DIR = @SYSTEM_HEADER_DIR@
+with a version that gets rid of extra ..'s, e.g.
+ SYSTEM_HEADER_DIR = `echo @SYSTEM_HEADER_DIR@ | sed -e :a -e "s,[^/]*/\.\.\/,,;ta"`
+(hey, that's the first time I've ever used a label in a sed script; thanks to the sed faq
+for explaining the :a ... ta method of looping to repeat a search-and-replace until it doesn't match.)

+
+This seems to solve the missmatch. Would it be possible to test it on
+bigger testcase and if it works distile a testcase that don't use
+file IO so it is more suitable for gcc regtesting?
