I expect that people wll jump on you, saying
"Don't check in generated files."

Not me: I sometimes check in generated files,
e.g. to protect against the possibility
of some unanticipated dependency like a change
in compiler version resulting in the inability
to regenerate exactly the historical files.

I do, too, but not in the development tree.  When such things are needed,
there's a separate release tree that gets the important results of a build.
They're checked in as part of the build or release automation, and
developers needn't deal with the problem on a day to day basis.

There are also circumstances in which it makes sense to check in the
compiler, linker, other tools, and even a list of OS patches and
configuration items (but not the whole OS).

If only 10-50 lines are actually changing, then it doesn't matter that
it's generated; it should be a tiny diff, anyway.  It's no different
than checking in a 3000+ line plain source file.

I often check in prebuilt Windows binaries and libraries, since that
environment is painful to automate.
