The patch doesn't work. With 4.9-20130421 + the patch I get: /tmp/objdir/./prev-gcc/xg++ -B/tmp/objdir/./prev-gcc/ -B/tmp/install49/x86_64-unknown-linux-gnu/bin/ -nostdinc++ -B/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -B/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/libsupc++/.libs -I/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/include/x86_64-unknown-linux-gnu -I/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/include -I/tmp/gcc-4.9-20130421/libstdc++-v3/libsupc++ -L/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs -L/tmp/objdir/prev-x86_64-unknown-linux-gnu/libstdc++-v3/libsupc++/.libs -c -DIN_GCC_FRONTEND -g -O2 -gtoggle -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Werror -DHAVE_CONFIG_H -I. -Ifortran -I/tmp/gcc-4.9-20130421/gcc -I/tmp/gcc-4.9-20130421/gcc/fortran -I/tmp/gcc-4.9-20130421/gcc/../include -I/tmp/gcc-4.9-20130421/gcc/../libcpp/include -I/home/mikpe/pkgs/linux-x86_64/gmp-5.1.1/include -I/home/mikpe/pkgs/linux-x86_64/mpfr-3.1.2/include -I/home/mikpe/pkgs/linux-x86_64/mpc-1.0.1/include -I/tmp/gcc-4.9-20130421/gcc/../libdecnumber -I/tmp/gcc-4.9-20130421/gcc/../libdecnumber/bid -I../libdecnumber -I/tmp/gcc-4.9-20130421/gcc/../libbacktrace /tmp/gcc-4.9-20130421/gcc/fortran/module.c -o fortran/module.o /tmp/gcc-4.9-20130421/gcc/fortran/module.c:78:18: fatal error: zlib.h: No such file or directory #include <zlib.h> Note the absence of any -I directive to pick up the internal zlib.
