Re: [cygnus.gas2] binutils bug: config.guess

[Ben Elliston <bje@cygnus.com>]

I wasn't entirely sure where I should send this, as it seems to be
specific to binutils.  It's a response to Carlo Wood's bug report about
config.guess in the binutils package:

This is quite a specific case that causes this to fail.  Since it only
occurs when there is a subdirectory named `ld' (as there is in binutils)
and then only when you have `.' in front of the path to your ld program, I
am inclined to suggest a binutils-only modification to config.guess that
just warns:

	if test -d `which ld`
	  echo "Error: cannot invoke ld"
	fi

.. or something to that effect.  I don't think I am prepared to hack up
config.guess to cater for this, unless someone has a more elegant
solution.

I feel this is a valid complaint; I will put it onto the heap. Thanks,
