+# Transforms event_rpcgen.py failure into success for make, only if
+# regress.gen.c and regress.gen.h already exist in $srcdir.  This
+# is needed for "make distcheck" to pass the read-only $srcdir build,
+# as with read-only sources fresh from tarball, regress.gen.[ch] will
+# be correct in $srcdir but unwritable.  This previously triggered
+# Makefile.am to create stub regress.gen.c and regress.gen.h in the
+# distcheck _build directory, which were then detected as leftover
+# files in the build tree after distclean, breaking distcheck.
+# Note that regress.gen.[ch] are not in fresh git clones, making
+# working Python a requirement for make distcheck of a git tree.
