Unable to install Ruby 2.3.3 on Cygwin on Windows Server 2008

[bradoc]

rvm install 2.3.3 fails with the following output;

ruby-2.3.3 - #compiling...........
Error running '__rvm_make -j1',
please read /home/bradoc/.rvm/log/1507520496_ruby-2.3.3/make.log
There has been an error while running make. Halting the installation.

The make.log file is here

The critical failure seems to be related to this;

error: unknown type name ‘Dl_info’

which seems to be something to do with the C libraries, but I am unsure how to troubleshoot this further.

I have been able to successfully install Ruby 2.4.0 with my current setup but need 2.3.3 for compatibility reasons.
