Do we already have a hard dependency on perl for all non-Windows builds?
I know it's been discussed but I don't recall. If so, back to what version?
I think the policy is we require perl for building from a git pull,
but not for building from a tarball.  Thus, any files that perl is used
to produce have to be shipped in tarballs.

However, there definitely *is* a hard requirement on perl for Windows
builds, even from tarballs, and I thought this patch was only about
the Windows build?


Michael's patch proposes to replace the use of sed to generate probes.h with the perl equivalent everywhere. That has the advantage that we keep to one script to generate probes.h, but it does impose a perl dependency.

We could get around that by shipping probes.h in tarballs, which seems like a perfectly reasonable thing to do. If we don't like that we can fall back to using the perl script just for MSVC builds.
