Sorry, I misread your question the first time as asking for building in a
different directory from the source directory.  As of November 8th 1999, the
mainline GCC should have the ability to figure out where the installation
directory is by looking at how it was invoked.  Ie, if the compiler was
originally compiled to be installed in:

	/usr/compilers/gcc-today

and you renamed /usr/compilers/gcc-today to /usr/compilers/gcc-2000-07-05, and
invoked the compiler as:

	/usr/compilers/gcc-2000-07-05/bin/gcc ...

it would automatically try to find the compiler proper, etc. in

	/usr/compilers/gcc-2000-07-05/bin/../lib/gcc-lib/i686-linux/2.96/

If it doesn't find the compiler tools there, it will fall back to the compiled
in location.  You can also use the -I, -B, -b, -V options and/or the
GCC_EXEC_PREFIX environment variable to specify where the installation
directories are.
