Yamada-san,
I have a question on the current top level Makefile. There are
following lines, I have trouble to understand "firstword x$(MAKEFLAGS)"
in 2nd line, why there is a 'x' there?
ifneq ($(filter 4.%,$(MAKE_VERSION)),) # make-4
ifneq ($(filter %s ,$(firstword x$(MAKEFLAGS))),)
quiet=silent_
tools_silent=s
endif
else # make-3.8x
ifneq ($(filter s% -s%,$(MAKEFLAGS)),)
quiet=silent_
tools_silent=-s
endif
endif
I already read & understand your patch[*] and know these lines will be
modified, but I have spent quite a few days on understanding it, so I
still want to know the purpose of 'x'.
