Dear gcc-help@gcc.gnu.org

I tried the next URL procedure.
http://quox.org/install/gnu/gcc-4.0.0.html

Configuration was OK,but make procedure alerted next message.

make[1]:Entering directory
'/home/gcc-4.0.0/build-x86_64-unknown-linux-gnu/libiberty'
make[1]:*** 'regex.o' に必要なターゲット '../include/ansidecl.h'
をmakeするルールがありません。中止。
make[1]:Leaving directory '/home/
/gcc-4.0.0/build-x86_64-unknown-linux-gnu/libiberty'
make:***[all-build-liberty] エラー 2

My PC env.:Turbolinux for EM64T.
