It's actually an AFS_CCRULE that you should be invoking.
My suspicion is that this is down to suffix rules. POSIX make should
have a default .y.c suffix rule, which is used to produce
error_table.c. Our .c.o rule then uses that to build error_table.o.
However, your make seems to be going directly from .y to .o (going via
y.tab.c on the way). This suggests to me that it has a .y.o rule, which
uses its own compiler line, and so doesn't pick up AFS_CCRULE at all.
You may be able to fix this by explicitly defining a y.c rule - although
I'm not sure if that will 'win' over a default .y.o one.
I don't think we want to rely on any of the default suffix rules. Does
BSD support:
.SUFFIXES:
to disable all built-in suffix rules?
It does, though in this case I was able to proceed by adding an explicit
dependency on error_table.c to the error_table.o rule (gerrit/3145).
