Normally, of course, you wouldn't run exactly those commands. But I'd expect
  rm: missing operand
rather than this a fork() failure.

In this situation, running 'rebase' would often fix the problem.

Were any MSYS programs (such as bash) running when you tried it?

Did it print any diagnostics?

Did you try a different base address than 0x67000000?

Have you ruled out BLODA?

'mingwrt' contains headers and import libraries for windows-native
programming, so it doesn't have fork(). MSYS has its own distinct
runtime library which would include fork().
