Hi William,
Such patches should be sent to mailing-list and not private to my
person. So I forward it to public mailing-list.
I had a short glance about your changes and have some objections to
the '--disable-multilib' option changes in documentation.
JonY will take care about more detailed review for it.
Regards,
Kai

slightly for building the mingw-w64 cross compiler on Linux.
+The mingw-w64 cross compilers consists in a few basic packages, among which
+binutils, gcc, and windows headers, compiled in a special way. Once it is
+operational, it forms the base to compile the packages of your project.
+A collection of packages built on top of mingw-w64 can be found in fedora,

You have two main choices to make building the cross-compiler toolchain:
-1) To build with default standard multilib (allows for building to a 32-bit
-alternate target, using Mingw-w64's lib32), or to disable multilib. Multilib
-is installed by default, if you don't want it, you have to explicitly disable
-it by passing --disable-multilib to configure, i.e.
- ../path/to/configure --disable-multilib
+1) To build a cross-compiler that will generate 32 bits binaries, 64 bits
+binaries, or that will be multilib enabled (so that the toolchain can target
+both, using Mingw-w64's lib32).
+ * 32 bits only : use options such as '--host=i686-w64-mingw32',
+ '--target=i686-w64-mingw32' or '--disable-multilib'
+
+ * 64 bits only : use options such as '--host=x86_64-w64-mingw32',
+ '--target=x86_64-w64-mingw32' or '--disable-multilib'
+
+ * multilib enabled : use options such as '--host=x86_64-w64-mingw32',
+ '--target=x86_64-w64-mingw32','--enable-targets=all','--enable-lib32' or
+ '--enable-targets=x86_64-w64-mingw32,i686-w64-mingw32'

+It is recommanded to use the two first options, as the third one will require
+more knowledge to use it properly. In the rest of this howto, examples will be
+provided for the '64 bits only' option and for the 'multilib enabled' option.
+For the '32 bits' option, please replace 'x86_64-w64-mingw32' by
+'i686-w64-mingw32' wherever you see it.

requires no setting changes, or to build to a sysroot you designate. /usr/local
