Hello, Where do you see such code, https://github.com/ruby/ruby/blob/master/lib/mkmf.rb doesn't seem to have it. In any case, it's not a good idea to use `CONFIG` in `extconf.rb`, use `RbConfig::CONFIG` instead (like everywhere else), that's always expanded.

Hello Ruby Dev Team, With Ruby 3.2.2, gem install fails because in rbconfig.rb, MAKEFILE_CONFIG's $(target_os) is not expanded (whereas CONFIG's is expanded correctly).
The inline doc in mkconfig.rb states that the caller can expand MAKEFILE_CONFIG's values by calling RbConfig::expand().
However, ruby-shadow gem's Makefile generator -- extconf.rb -- does not call expand and directly uses mkmf.rb's CONFIG instance (which is RbConfig::MAKEFILE_CONFIG), because of which $(target_os) does not get expanded. This causes ruby-shadow gem install to fail with Ruby 3.2.2.
Would the Ruby Dev Team accept the following proposal to fix mkconfig.rb, so that the generated rbconfig.rb instantiates MAKEFILE_CONFIG AFTER CONFIG's values have been expanded?
# Existing code... CONFIG.each_value do |val| RbConfig::expand(val) end # Move instantiation of MAKEFILE_CONFIG after expanding CONFIG's values. MAKEFILE_CONFIG = {} CONFIG.each{|k,v| MAKEFILE_CONFIG[k] = v.dup}
If we fix it in mkconfig.rb, we can avoid callers having to explicitly call expand for MAKEFILE_CONFIG's values.
