* I made the following modifications, be sure to readd these when

* upgrading these files.

* Added this comment.

* Added "gaim_ ## " to the namespace

* Changed the lib macro to use /lib/gaim instead of just /lib

* (why does gaim do that in the -DLIBDIR autoconf thing anyway?)

* BinReloc - a library for creating relocatable executables

* Written by: Mike Hearn <mike@theoretic.com>

* Hongli Lai <h.lai@chello.nl>

* http://autopackage.org/

* This source code is public domain. You can relicense this code

* under whatever license you want.

* See http://autopackage.org/docs/binreloc/ for

* more information and how to use this.

* NOTE: if you're using C++ and are getting "undefined reference

* to br_*", try renaming prefix.c to prefix.cpp

/* WARNING, BEFORE YOU MODIFY PREFIX.C:

* If you make changes to any of the functions in prefix.c, you MUST

* change the BR_NAMESPACE macro.

* This way you can avoid symbol table conflicts with other libraries

* that also happen to use BinReloc.

* Example:

* #define BR_NAMESPACE(funcName) foobar_ ## funcName

* --> expands br_locate to foobar_br_locate

#undef BR_NAMESPACE

#define BR_NAMESPACE(funcName) gaim_ ## funcName
