That would seem to require fewer changes, and it looks strange for `getTime` to call `stat_getElapsedTime` which calls back to `getProcessElapsedTime`. For the threaded patch: are we getting `HAVE_CLOCK_GETTIME` from `ghcautoconf.h`? Perhaps it ought to come from the base package's `HsBaseConfig.h`?

Comment:
When you're doing batch linking, you have to specify all the packages
manually, like this:
{{{
$ ghc -o test test.o -package haskell98
}}}
This is documented with the `-package` flag:
[http://www.haskell.org/ghc/docs/latest/html/users_guide/packages.html].
It has always been like this, except that there are two recent changes
which apparently tripped you up here: now `--make` is the default, which
is why when you give the `.hs` file it works, and the `haskell98` package
used to be linked in by default (now it isn't).
