Problems compiling gcc-3.0

[Steve Maughan <steve dot maughan at bigfoot dot com>]

Hi, I'm having problems compiling gcc-3.0... I'm not using any special 
configure flags or anything, just a standard build. It says:

../../gcc-3.0/gcc/gcc.c: In function `execute':
../../gcc-3.0/gcc/gcc.c:2714: `prus' has an incomplete type
../../gcc-3.0/gcc/gcc.c:2715: `RUSAGE_CHILDREN' undeclared (first use in
this function)
../../gcc-3.0/gcc/gcc.c:2715: (Each undeclared identifier is reported
only once
../../gcc-3.0/gcc/gcc.c:2715: for each function it appears in.)
../../gcc-3.0/gcc/gcc.c:2716: invalid use of undefined type `struct
rusage'
[snip]
../../gcc-3.0/gcc/gcc.c: At top level:
../../gcc-3.0/gcc/gcc.c:214: storage size of `rus' isn't known
../../gcc-3.0/gcc/gcc.c:214: storage size of `prus' isn't known
make[1]: *** [gcc.o] Error 1
make[1]: Leaving directory `/usr/src/Compiler/object/gcc'
make: *** [all-gcc] Error 2

and fails there.

Also, I get a lot of these warnings:

>In file included from /usr/include/string.h:346,
>                 from ../../gcc-3.0/gcc/system.h:101,
>                 from c-parse.y:36:
>/usr/include/bits/string2.h: In function `__stpcpy_small':
>/usr/include/bits/string2.h:611: warning: pointer targets in return
>differ in signedness

...although it still compiles past these warnings.

Does anyone know what the problem is? I'm trying to compile it with
gcc-2.95.3.
