### Remove GNU make implicit rules
## This speeds things up since we don't need to look for and stat() a
## "foo.c,v" every time a rule referring to "foo.c" is in play. See
## "make -p -f/dev/null | grep ^%::'".
%:: %,v
%:: RCS/%,v
%:: RCS/%
%:: s.%
%:: SCCS/s.%
## Likewise delete default $(SUFFIXES). See:
##
## info make --index-search=.SUFFIXES
.SUFFIXES:
### Flags affecting all rules
# A GNU make extension since gmake 3.72 (released in late 1994) to
# remove the target of rules if commands in those rules fail. The
# default is to only do that if make itself receives a signal. Affects
# all targets, see:
#
# info make --index-search=.DELETE_ON_ERROR
.DELETE_ON_ERROR:
### Global variables
## comma, empty, space: handy variables as these tokens are either
## special or can be hard to spot among other Makefile syntax.
comma := ,
empty :=
space := $(empty) $(empty)
