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:

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
?
