Compiler Search Path

[Felix Daners]

Hi

I have configured and built a cross
compiler running in a mingw32 environment.

Does anybody know how to change the compiler
search path in this environment?

I just want to change the prefix.

example:
the compiler is configured with
  --prefix=/opt/cross
  --target=arm-elf
  --host=i386-mingw32
  --build=  some linux machine

now I have moved the compiler an the libraries
to the win2000 box.
this all works fine as long as the compiler ist installed
in a directory which fits the --prefix=/opt/cross
wich in this example is

C:\opt\cross

And now the question:

How can I change the installation directory
without recompiling the compiler with an other
prefix switch?
For example I want to install on
C:\gcc-armelf
instead of C:\opt\cross

What about Registry entries?
What about environment variables?

Thanks
