Subject: [Patch, Darwin + doc] alias mconstant-cfstrings to fconstant-cfstrings and document the flag.
Date: Mon, 14 Feb 2011 17:08:00 -0000 [thread overview]
Message-ID: <B4F496F4-F31D-41D2-8942-1F0AEFBD7BBF@sandoe-acoustics.co.uk> (raw)
The Apple system tools expect the "-mconstant-cfstrings" to be "-
fconstant-cfstrings".
the patch below aliases this, for compatibility and provides an entry
in invoke.texi
OK for trunk?
Iain
