I just hit the build error by make on my machine Fedora 34 on the latest master 9ed196e4876dd15991feee27e7dce1b67783060f .

I could build on the master 1cb5a669d39fe741388be7ac45fc88c336b097cf last week.

So, the cause could be a commit between those commits.

$ git diff 1cb5a669d39fe741388be7ac45fc88c336b097cf..9ed196e4876dd15991feee27e7dce1b67783060f

I see the build error happens on the following commit. While it works on the previous commit. Maybe the commit causes the build error. Do you have any idea to fix it?

Build rubyspec CAPI extensions

@nobu (Nobuyoshi Nakada) What's the reason to build C API specs extensions eagerly?
Can't we let ruby/spec build them at runtime as normal?

The target at defs/gmake.mk:359 is spec/%, seems miss-firing *.c files.
I've missed the in-place build case.

As compilation warnings were discarded and ignored.

Applied in changeset git|e3dcb6204d66c62aedaf94cac336d93d0275ce2c.

---

Run only directories or *_spec.rb files only by mspec [Bug #18072]

Not to match *.c files under spec/ruby/optional/capi/ext, in the
case of in-place build.

Thanks for the fix! I confirmed I was able to build on the latest master.
