In Coreutils, which uses --enable-silent-rules by default, I see:
$ make
GEN .version
GEN lib/alloca.h
GEN lib/arpa/inet.h
GEN lib/configmake.h
if test -n 'gcc'; then \
/usr/bin/mkdir -p 'lib/crc-tmp' \
&& abs_srcdir=`cd ./lib/. && pwd` \
&& (cd 'lib/crc-tmp' \
&& gcc -g -O2 -o crc-generate-table
$abs_srcdir/crc-generate-table.c) \
&& 'lib/crc-tmp/crc-generate-table' ./lib/crc-sliceby8.h-t \
&& rm -rf 'lib/crc-tmp' \
&& mv ./lib/crc-sliceby8.h-t ./lib/crc-sliceby8.h; \
fi
GEN lib/ctype.h
I've applied the attached patch which uses $(AM_V_GEN) like we do for
the header substitutes.
$ make
GEN .version
GEN lib/alloca.h
GEN lib/arpa/inet.h
GEN lib/configmake.h
GEN lib/crc-sliceby8.h
GEN lib/ctype.h
