>Description:
I built gcc-3.0.2 ('C' language only) just fine with gcc-3.0.1.
Now when I bootstrap gcc-3.0.2 ('C', 'C++', 'Java' languages only), I get a
 segmentation fault during the "libmath" build process:

make[4]: Nothing to be done for `all'.

I'm running on a RedHat 6.0 base system with 2.4.10 kernel, glibc-2.2.4, and binutils-2.11.2. 
	
>How-To-Repeat:
I get this problem when I build gcc-3.0.2 with these options:

$ ./configure --prefix=/usr --enable-languages=c,c++,java --enable-shared --enable-threads=posix
