I prefer to use hyphens, when possible (GNU make only), but obviously that is not portable to all Make programs. So, when I remember that maint.mk is used only if/when GNU Make is available, I tend to use hyphen -- assuming it's used only in that file, and not used in any Makefile.am. I suspect that some pieces of that file migrated from Makefile.am, where portability dictated the use of underscores.
