 Oh how true - an organisation I worked for some years back had the source code matching a custom package that was running at a certain customer, but not the build environment (that machine with that precise operating system patch level, compiler patch level etc.).

When the customer said thay'd pay for the source to look after if themselves, rather than continue to pay maintenance, they insisted that a new build be run to prove that exact byte for byte identical binaries to what they were running could be re-created  - a wise move indeed - it took 8 man months to re-create that build environment (and that was only possible because I insisted we archive all the patches to the system, compilers and libraries).

	Horror stories abound about organizations that need to make some minor patch or change to source code of a popular product for some important customer even just a few years after its release and nobody can find the right source code or the right build environment (compilers, libraries, OS etc and the hardware they ran on) or if they can be found it takes many many hours of expensive time and talent to reconstruct the right stuff to actually make a code image that matches what is shipping.
