Hi Anya,

Looking at your specific example:-

A released product is made up of components which are built using specific
tools ... if you change the compiler you may introduce defects to your
code which are due to the binaries produced by defects in the compiler.
I've actually experienced this one in a previous role where as a sysadmin
we (unthinkingly) patched the central copy of the compiler in order to fix
an issue one team was having ... this however broke the build of one of
another team who were unknowlingly relying on the defect for their code to

As an SCM best practice the version of the tools used to build your
released product should be tracked alongside your source code (IMHO).

Consequently your statement concerning developers wanting to be able to
modify (as an example) makefiles so that they can change the compiler ...
this is exactly the kind of situation you'd want to track in an SCM
