You need to set a -D... flag while compiling so that it would be used... therefore, it would (could ?) be used with other platforms in the 'default way' and with binReloc with linux. I am not 100% sure about this, but I might take a look. By now I heard KDELibs has something like this and I would like to see my 'toolkit of choice' to have such options.... I will study the subject and post any news if anyone opposes. BTW, although your approach may be valid for executable files, it wouldn't work with libraries. well... I think that's all I have to say now. Please forgive my poor english as it is not my primary language.
