Hi,
We've got an unusual build scenario, when user has a jdk-windows build
setup with a pre-configured cygwin environment (and a batch script to
run the build), but want to start this build on a remote machine that
runs SSH server inside msys2 environment.
In this scenario, with batch script started over msys2 SSH, autoconf
fails on OS detection, and the patch below (submitted by github user
quanah) is needed to fix that.
If someone thinks that such change is a good idea - I can file a Jira
issue and prepare a webrev for it.
Please note, that this patch is not intended to enable msys2 to actually
run jdk build - msys2 environment is used only to start the build that
uses cygwin.
Some details on a relationship between msys, msysgit, msys2 and cygwin:
