+ syntax-check: keep one maint.mk rule in sync with its header
+ * Makefile (sc_check_sym_list): Add a rule to prevent a repeat
+ of the bug Eric has just fixed, with today's commit 25e4c2ec.
+ I prefer to avoid temporary files here, so use <(...), but that
+ is not supported by /bin/sh, so...
+ (SHELL): Define to /bin/bash.

+ Suggested by Jim Meyering.
