Moving installed gcc version to other path

[Hard Maker <hardmaker@xxxxxxxxx>]

Hi, I trying to move binary version of gcc from the installed path (this 
was defined throw --prefix at build time) to other path, but I want 
update the the search path of gcc to the new locations. How can I do? 
Wath files or options I need to write? Where can I read about?
This question is not just for linux, I'm trying to build gcc in linux 
for run under windows system using mingw and I don't know how can update 
the search paths for librarys.
Thank's very much
