unicode_east_asian_fw_table.h should not be compiled standalone, similarly
to unicode_combining_table.h, but cpluspluscheck did not get the memo.
Oversight in
bab982161.
Per report from Tom Lane
# Also not meant to be included standalone.
test "$f" = src/include/common/unicode_combining_table.h && continue
+ test "$f" = src/include/common/unicode_east_asian_fw_table.h && continue
# We can't make these Bison output files compilable standalone
# without using "%code require", which old Bison versions lack.
