+Subject: [PATCH 1/3] Chez Scheme: Fix build on GNU/Hurd
+
+Mostly GNU/Hurd should take the same options as GNU/Linux. One
+difference is that the Hurd does not define macros such as `PATH_MAX` or
+`NOFILE`, because it avoids imposing arbitrary limits on such resources.
+This patch provides alternatives for localized uses of those constants,
+but it accepts the pervasive use of `PATH_MAX` in finding bootfiles for
+now. See https://www.gnu.org/software/hurd/hurd/porting/guidelines.html.
+
+(cherry picked from commit 87eee6e2adb8c6bc11e60619c706fa6295096085)
