Just some random thoughts, and commentary on a couple of speed bumps.

I have ld from binutils 2.13 installed in /usr/local/bin and GCC 3.2.1 
installed in /usr/local/.... I have deleted /usr/bin/gcc, /usr/bin/g++, 
/usr/local/bin/cc and /usr/local/bin/c++. This gives me a system C compiler 
called cc and the GNU addon called gcc, just like every other computer I use. 
This distinction becomes important because of ABI changes in C++ (not that I 
know what those changes are).

The C compiler seems to work really well. At least one codegen bug has been 
fixed, and I'm going to start checking one or two other codegen bugs I found 
in 2.95.3.

The C++ compiler seems to have a problem because binaries it builds use 
libgcc, and it looks as if the shared version of libgcc is built with non-PIC 
code. The error I get is 'Undefined symbol "" (reloc type = 12, symnum = 21)', 
but I haven't bothered trying to find out what this means. Using 
-static-libgcc works, and I have noticed that seems to use the same 
.o files for libgcc.a and

The NetBSD gcc prints out its version number as '2.95.3' while GCC 3.2.1 
prints several lines of text and warranty information. This causes 
pkgsrc/lang/gcc/ to become unhappy.
