When I try to emerge sys-devel/gcc-4.8.4 on ppc I run into the following compiler error: powerpc-unknown-linux-gnu-g++ -c -DEFAULT_SSP -DHOST_GENERATOR_FILE -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 -DHAVE_CONFIG_H -I. -I. -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/. -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../include -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../libcpp/include -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../libdecnumber -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../libdecnumber/dpd -I../libdecnumber -I/var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../libbacktrace -DCLOOG_INT_GMP /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c -o gengtype.o In file included from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c:26:0: /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:500:34: error: declaration of C function 'const char* strsignal(int)' conflicts with extern const char *strsignal (int); ^ In file included from /usr/lib/gcc/powerpc-unknown-linux-gnu/4.8.4/include/g++-v4/cstring:42:0, from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:205, from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c:26: /usr/include/string.h:563:14: error: previous declaration 'char* strsignal(int)' here extern char *strsignal (int __sig) __THROW; ^ In file included from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:645:0, from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c:26: /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/../include/libiberty.h:110:36: error: new declaration 'char* basename(const char*)' extern char *basename (const char *); ^ In file included from /usr/lib/gcc/powerpc-unknown-linux-gnu/4.8.4/include/g++-v4/cstring:42:0, from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:205, from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c:26: /usr/include/string.h:600:26: error: ambiguates old declaration 'const char* basename(const char*)' extern "C++" const char *basename (const char *__filename) ^ In file included from /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.c:26:0: /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:289:56: error: 'CHAR_BIT' was not declared in this scope ? ~ (t) 0 << (sizeof(t) * CHAR_BIT - 1) : (t) 0)) ^ /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:290:44: note: in expansion of macro 'INTTYPE_MINIMUM' #define INTTYPE_MAXIMUM(t) ((t) (~ (t) 0 - INTTYPE_MINIMUM (t))) ^ /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/system.h:294:20: note: in expansion of macro 'INTTYPE_MAXIMUM' # define UCHAR_MAX INTTYPE_MAXIMUM (unsigned char) ^ /var/tmp/portage/sys-devel/gcc-4.8.4/work/gcc-4.8.4/gcc/gengtype.h:455:23: note: in expansion of macro 'UCHAR_MAX' CHAR_TOKEN_OFFSET = UCHAR_MAX + 1, ^ Makefile:1070: recipe for target 'gengtype.o' failed make[3]: *** [gengtype.o] Error 1 make[3]: Leaving directory '/var/tmp/portage/sys-devel/gcc-4.8.4/work/build/gcc' Makefile:4153: recipe for target 'all-stage1-gcc' failed make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory '/var/tmp/portage/sys-devel/gcc-4.8.4/work/build' Makefile:17631: recipe for target 'stage1-bubble' failed make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory '/var/tmp/portage/sys-devel/gcc-4.8.4/work/build' Makefile:17946: recipe for target 'bootstrap-lean' failed make: *** [bootstrap-lean] Error 2 # emerge -pqv '=sys-devel/gcc-4.8.4::gentoo' [ebuild R ] sys-devel/gcc-4.8.4 USE="altivec cxx fortran graphite nptl openmp -awt -debug% -doc (-fixed-point) -gcj -go (-hardened) (-libssp) -mudflap (-multilib) (-multislot) -nls -nopie -nossp -objc -objc++ -objc-gc -regression-test -sanitize -vanilla" Reproducible: Always

All of these errors are due to clashing declarations which should be taken care of by <string.h>. From your emerge info though, it seems that you have gcc-4.8.4 already installed. What triggered the rebuild is -debug%. Can you play around with that flag and see if enabling/disabling makes a difference. (I have access to ppc, but $real_life.)
you need to repo sync and get the latest patchset *** This bug has been marked as a duplicate of bug 487398 ***
