-+#define PGRP_PIPE 1
+Description: Set PGRP_PIPE unconditionally on Linux, reproducibly
+ The original fix to #224543 involved defining this unconditionally in
+ config-bot.h. Unfortunately, upstream has a check in configure.ac that defines
+ this conditionally in config.h, which makes the bash-builtins package 
+ unreproducible between different kernels. Here, we adopt a different approach,
+ which is to turn upstream's define into an uncondtional define. Then we can
+ also avoid touching config-bot.h.
+ .
+ More generally, installing config.h is bad practise because it fixes
+ build-time variables into everyone's installations, but that is a problem for
+ another day.
