[ruby-core:92208] [Ruby trunk Bug#15754] MinGW build/compile failure with Ruby 2.5.5, but 2.6.2 & trunk ok

Issue #15754 has been updated by MSP-Greg (Greg L).


As to commits, see:

r64620 - Declare as gnu_printf on mingw
https://github.com/ruby/ruby/commit/c115b39e033979bac7cfd2db5735549430dc14f7

and

r64630 - use mingw ANSI stdio
https://github.com/ruby/ruby/commit/1cf2bb4b2085758112503e7da7414d1ef52d4f48

Obviously, they'd need to be modified for 2.5 & 2.4, but since both are active branches, a backport would be helpful.

Ok to close...

As many of you may recall, I'm not a c type, especially regarding build errors.  Recently tried to build 2.5.5 locally, and I get errors similar to the below.  I do not have any errors using the same build code (ruby-loco) when building 2.6.2 or trunk.

Any help/suggestions would be appreciated...  Thanks, Greg
