Имеем gcc3.3-3.3.3-alt1 (не приложены патчи deb-ada-gcc-name и
deb-libstdc++-doclink).  Пытаюсь собрать кросскомпилятор в
i386-mingw32msvc, вылезает следующая ошибка в самом начале stage2:

И действительно, sys/wait.h в mingw32-runtime отсутствует и не
было его никогда там.  В то же время gcc-3.3 прекрасно
собирается.  Я совсем дурак или у меня просто руки слегка
кривоваты?

Секция %build выглядит следующим оразом (shamelessly stolen from
gcc3.3.spec):

%build
for f in */configure.in; do
	(cd "${f%/*}" && [ configure.in -nt configure ] && autoconf)
done
for f in */Makefile.am; do
	(cd "${f%/*}" && [ Makefile.am -nt Makefile.in ] && automake)
done
