I tried also with an older version of gcc (4.8.2) and got the same problem in different source file, this time on genconstants.c. Check the logs: make[3]: Entering directory `/home/ftp/pub/gcc-build/gcc' g++ -c -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE -I. -Ibuild -I../../gcc-4.8.2/gcc -I../../gcc-4.8.2/gcc/build -I../../gcc-4.8.2/gcc/../include -I../../gcc-4.8.2/gcc/../libcpp/include -I../../gcc-4.8.2/gcc/../libdecnumber -I../../gcc-4.8.2/gcc/../libdecnumber/bid -I../libdecnumber -I../../gcc-4.8.2/gcc/../libbacktrace \ -o build/genconstants.o ../../gcc-4.8.2/gcc/genconstants.c In file included from ../../gcc-4.8.2/gcc/genconstants.c:28: ../../gcc-4.8.2/gcc/system.h:205:20: cstring: No such file or directory ../../gcc-4.8.2/gcc/genconstants.c: In function `int print_md_constant(void**, void*)': ../../gcc-4.8.2/gcc/genconstants.c:38: warning: unused parameter `void*info' ../../gcc-4.8.2/gcc/genconstants.c: In function `int print_enum_type(void**, void*)': ../../gcc-4.8.2/gcc/genconstants.c:51: warning: unused parameter `void*info' make[3]: *** [build/genconstants.o] Error 1 make[3]: Leaving directory `/home/ftp/pub/gcc-build/gcc' make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory `/home/ftp/pub/gcc-build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/ftp/pub/gcc-build' make: *** [all] Error 2
