Failed to build libobjc/gc.c, can't find gc.h

When trying to build gcc-3.1-20020202 (CVS Sun Feb 3 06:27:10 UTC 2002), I
get an error in libobjc/gc.c:

The bootstrap was with binutils (CVS Sun Feb  3 06:32:56 UTC 2002) on a debian sparc woody system.

configure was run like this:
../configure --with-gcc-version-trigger=/share1/gcc-dev/gcc/gcc/version.c --host=sparc-linux --enable-languages=c,c++,java,f77,proto,objc --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --enable-shared --with-gnu-as --with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-included-gettext --enable-threads=posix --with-cpp-install-dir=bin --enable-objc-gc --verbose --norecursion 

Note the --enable-objc-gc option.
