   Nonsense.  I have an LD_PRELOAD'ed library I use every day that's source 
   and binary compatible between glibc 2.0 and 2.1, and source compatible 
   between linux and solaris.

Then you are very lucky.  Overloading functions with an LD_PRELOAD'ed
library is a very tricky business, and binary compatibility is not
guaranteed.
