I am new to this web site and found it quite hard to find and go back to where I posted my original question and see what others posted against it. I ended up doing 'Super Search' for the subject line to locate them, and then click on those to see what is posted in response. I then struggled to find out how to post this back. Hope this goes out. Sigh!
Thanks a lot for your responses. Ya, there is a -m32 vs -m64 option to gcc. However in the generated Makefile I see lot of things like X86_64 etc etc which look like places where things get installed. I don't think just by changing compile option from -m64 to -m32 will do it everything right. So thought of asking around. Will try more.
