--- Comment #7 from Jan-Benedict Glaw <jbg...@lug-owl.de> --- I'm not 100% sure, but I guess this fix breaks building GCC on gcc111.fsffrance.org . All build details can be found here: http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=218196 The actual error message is: g++ -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -Woverloaded-virtual -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -I. -I. -I/home/jbglaw/repos/gcc/gcc -I/home/jbglaw/repos/gcc/gcc/. -I/home/jbglaw/repos/gcc/gcc/../include -I/home/jbglaw/repos/gcc/gcc/../libcpp/include -I/opt/cfarm/gmp-latest/include -I/opt/cfarm/mpfr-latest/include -I/opt/cfarm/mpc-latest/include -I/home/jbglaw/repos/gcc/gcc/../libdecnumber -I/home/jbglaw/repos/gcc/gcc/../libdecnumber/dpd -I../libdecnumber -I/home/jbglaw/repos/gcc/gcc/../libbacktrace -o sh.o -MT sh.o -MMD -MP -MF ./.deps/sh.TPo /home/jbglaw/repos/gcc/gcc/config/sh/sh.c In file included from /home/jbglaw/repos/gcc/gcc/system.h:262:0, from /home/jbglaw/repos/gcc/gcc/config/sh/sh.c:27: /usr/include/unistd.h:201:41: error: declaration of C function 'off64_t lseek64(int, off64_t, int)' conflicts with extern off64_t lseek64(int, off64_t, int);
