This reminds me of why I never want to use an online compiler
service - never mind how hard companies push them.

If I need to do a bug-fix build of something that was released
2 (or more) years ago I want to use exactly the same toolchain
(warts and all) that was used for the original build.

If the compiler has changed I need to do a full test - just
in case it compiles some 'dodgy' code differently.
With the same compiler I only need to test the fix.
