I don't wish to go *that* far. Parallel make works fine for most of the
tree in 3.82, and shutting it off would penalize developers a lot.
It appears to me that the case that okapi is hitting is specific to the
ecpg preprocessor build rules, and indeed specific to the case where
preproc.c needs to be rebuilt. A .NOTPARALLEL in ecpg/preproc/Makefile
would probably be enough to fix it. (I'm a bit tempted to make the one
already added to ecpg/Makefile conditional on the make version, as you
suggest above, too.)
