387866Ssheldonh# Transforms event_rpcgen.py failure into success for make, only if
487866Ssheldonh# regress.gen.c and regress.gen.h already exist in $srcdir.  This
587866Ssheldonh# is needed for "make distcheck" to pass the read-only $srcdir build,
687866Ssheldonh# as with read-only sources fresh from tarball, regress.gen.[ch] will
787866Ssheldonh# be correct in $srcdir but unwritable.  This previously triggered
887866Ssheldonh# Makefile.am to create stub regress.gen.c and regress.gen.h in the
988282Ssheldonh# distcheck _build directory, which were then detected as leftover
1088282Ssheldonh# files in the build tree after distclean, breaking distcheck.
1187866Ssheldonh# Note that regress.gen.[ch] are not in fresh git clones, making
1287866Ssheldonh# working Python a requirement for make distcheck of a git tree.
