commit 2af1914b6ad673a2041cf94cc8e78e1bdec57a27
Author: Jeremy Drake <cyg...@jdrake.com>
Date: Wed Jun 25 16:42:08 2025 -0700
Cygwin: testsuite: add a mingw test program to spawn
This program is currently meant to test standard file handles and
current working directory (since these are settable via posix_spawn),
but could be extended to add additional checks if other cygwin-to-win32
process properties need to be tested.
