Help needed for installing gcc 4.0.3

[熊俊]

I'm installing gcc-core-4.0.3 on alpha-dec-osf. When executing the command "make
bootstrap", it encountered errors and stoped. The last lines of messages
displayed
on screen are as below:

checking whether times is declared... yes
checking for struct tms... yes
checking for clock_t... yes
checking for .preinit_array/.init_array/.fini_array support... no
checking if mkdir takes one argument... no
*** Configuration alphaev6-dec-osf1 not supported
Bootstrapping the compiler
gmake[1]: Entering directory `/home/d2805/jsy4681/usr/bak/build/gcc'
gmake[1]: *** No rule to make target `bootstrap'.  Stop.
gmake[1]: Leaving directory `/home/d2805/jsy4681/usr/bak/build/gcc'
gmake: *** [bootstrap] Error 2

The "Host/Target specific installation notes for GCC" (http://gcc.gnu.org/install/specific.html#alpha-dec-osf)
says that "As of GCC 3.2, versions before alpha*-dec-osf4
are no longer supported". Does this statement apply to gcc 4.x too? Could I work
around it and achieve the installation somehow?

Thanks in advance!
