Ситуация: нужно разобраться с eCos. Согласно http://ecos.sourceware.org/build-toolchain.html нужно собрать себе тулчейн. На шаге 4. Build and install GCC: make -w all install 2>&1 | tee make.out вываливается ошибка:

Перепробовал и новые 13.10, и старую 9.10, как в руководстве, и debian, но всегда эта же ошибка, причем не один я такой :). Форумы пестрят, но вот что откопалось: http://gcc.gnu.org/ml/gcc-help/2008-01/msg00040.html

Configure like this:

  CC='gcc -g -ansi -std=c89' /home/aph/gcc/gcc-3_2-branch/configure --enable-languages=c++

Build:

  make bootstrap

Подскажите, а как правильно «оформить» патч? Как использовать строку Configure like this:

CC='gcc -g -ansi -std=c89' /home/aph/gcc/gcc-3_2-branch/configure --enable-languages=c++

и что значит make bootstrap ?
