+Subject: [PATCH] tune: fix spurious clock_gettime reference
+
+When running the tune program, the generated gmp-mparam.h header might
+include an invalid line leading to build failures like so:
+In file included from .../gmp-impl.h:145:0,
+                 from mp_bases.c:4:
+../gmp-mparam.h:1:1: error: unknown type name 'clock_gettime'
+ clock_gettime is 1.000ns accurate
+
+This is because the tune source has one printf that is not protected
+by the verbose flag leading it to be written to the output.
+
+Credit to Conrad Kostecki for analysis.
