[PATCH 1/2] maint.mk: add leading "@" to quiet new "make syntax-check" rule |
Date: |

I tried out the latest from gnulib and saw that "make syntax-check"
was accidentally made too verbose.
Since this has happened too frequently, I've written
a syntax-check rule (we call it sc_maint) for gnulib itself
to help prevent a repeat.
