Issue #13496 has been updated by hsbt (Hiroshi SHIBATA).
Hi, Greg.
Thanks always about MinGW.
Can you give instructions to build your MinGW environment on Windows?
I will prepare MinGW environment for build ruby source.
----------------------------------------
Bug #13496: Patches for MinGW builds
https://bugs.ruby-lang.org/issues/13496#change-64533
* Author: MSP-Greg (Greg L)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v:
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Thanks to Nobu for [58448](https://github.com/ruby/ruby/commit/27ed9f1d290a6ff6b788976ea7139c608920ee1e), which led me to the probable cause of many (but not all) of the silent SEGV's I was having in test-all, which is the patch of `defines.h`.
Since appveyor is currently broken, and I'm not a *nix guy, does anyone know if the following two patches will break travis or appveyor? Or, a better way to do it?
These are the only two patches I have on the 'build' side. The other patches are only for test-all. I believe these should probably be backported to 2.4. Thank you.
