Re: Re: [PATCH 14/14] MINGW: config.mak.uname: auto-detect MinGW build from compiler

Hi Junio,

I didn't mean multiple uses of ?= for the same variable. I meant
multiple uses of (references to) the variable. I.e. wouldn't FOO and
BAR behave differently below?

FOO := $(shell random)
BAR = $(shell random)
all::
   echo $(FOO) and $(BAR)
   echo twice $(FOO) and $(BAR)

You're correct, of course, my mistake. I just tested with this:

	R ?= $(shell echo $$RANDOM)

	all:
		echo The values of $(R), $(R) and $(R)

and of course a "make" yields three different numbers. Sorry for missing
that.

So what we should do is something like

	ifeq ($(uname_S),)
		uname_S := $(shell uname -s)
	endif

even if repeating that pattern is kind of ugly...

Thanks for correcting my mistake,
Dscho
