Hmm, I need to fix this. I guess that configure should just check for 
-ffixed-ebp support. Fortunately, clang doesn't generate code that would 
trigger stack segment fault so the workaround is only needed for GCC.

Could you review and merge the trivial patches (4, 5, 6, 7) so that I 
don't need to resubmit everything?
