Hi Dan,

I think I didn't explain myself very well. I'd like to build a
gcc that "knows" where its files are by looking at an arbitrary
(specified at build time) environment variable. I think this is
what Wind River do in the gcc that is deleivered with Tornado -
it appears to use WIND_BASE.

The problem is that dirname(argv[0]) doesn't always work on
Unix - depends how the program is started. On Windows I think it's
always OK. I've observed that on Windows, gcc3.3 seems to be able
to find itself no matter where you copy it to, withou using
the sysroot option.

Dave
