Feature #13570: Using mkmf for ruby/spec C API specs

Hello all,
I am thinking to use mkmf to compile the C API specs.
https://github.com/ruby/ruby/blob/trunk/spec/rubyspec/optional/capi/spec_helper.rb
is getting pretty complex and hard to maintain.
I have a few questions:
* Does mkmf works well on Windows?
* What is a good way to compile a single .c file with mkmf to a given library file in another directory?
I tried this but I am not sure it's correct:
~~~ ruby
def compile_extension(name)
objdir = object_path
ext = "#{name}_spec"
lib = "#{objdir}/#{ext}.#{RbConfig::CONFIG['DLEXT']}"
require 'mkmf' # TODO: probably best to use a subprocess to avoid polluting the namespace
Dir.chdir(objdir) do
$srcs = ["#{extension_path}/#{ext}.c"]
$objs = ["#{extension_path}/#{ext}.o"] # should probably be in objdir but that does not seem to work
create_makefile(ext)
system "make"
end
lib
end
~~~
Alternatively, we can copy the needed files to a temporary directory, build there and copy the shared library back.
It's a bit more work but not a big deal either.
