--- Comment #7 from Bill Pringlemeir <bpringlemeir at gmail dot com> 2011-04-14 17:37:27 UTC --- After applying the patch, the tmp.c files builds without issues. #include <sys/bitypes.h> int main(void) { return 0; } $ arm-none-linux-gnueabi-gcc -flto -o tmp.x tmp.c It seems to be the same issues as Ramana has reported. Also my compiler has eglibc... but I think this is a binutils/ld issue. Did you want any more confirmation?
