+Subject: [PATCH] configure.ac: detect unusable termio operations
+
+Some termio operations are not actually usable on some
+architectures. For example, the TCGETA, TCSETA, TCSETAF and TCSETAW
+are defined with a reference to "struct termio" on alpha, hppa and
+sparc64, but "struct termio" is no longer defined since glibc 2.42,
+causing a build failure.
+
+Instead of using those operations as soon as they are defined, this
+commit checks more carefully that they are actually usable. This is
+done using a new m4 macro PY_CHECK_IOCTL.
