widl: [default] is an allowed attribute for union fields.
(Note: This patch was already applied before in order not to break ReactOS.)

- Alexandre Julliard <julliard@winehq.org> Tue, 1 Jul 2008
widl: Add some support for unencapsulated unions that need a conformance descriptor.

- Rob Shearman <robertshearman@gmail.com> Tue, 1 Jul 2008
widl: Increment the buffer offset by 8 for embedded pointers inside varying arrays in varying structures.

The 8 bytes are for the variance and offset and are added just before the array, as seen in the marshalling code in rpcrt4. No offset needs to be added for non-varying structures since the buffer mark is set after the conformance in marshalled or unmarshalled.

- Rob Shearman <robertshearman@gmail.com> Tue, 1 Jul 2008
widl: Check that the structure has been defined in check_remoting_args.

- Dan Hipschman <dsh@linux.ucla.edu> Tue, 1 Jul 2008
widl: Implement type redefinition checks.

This allows widl to catch type redefinitions and report an error, like MIDL. However, this does a better job than MIDL since it also reports the location of the originial definition, like GCC.

- Dan Hipschman <dsh@linux.ucla.edu> Tue, 1 Jul 2008
widl: Factor a small part of the grammar.

- Rob Shearman <robertshearman@gmail.com> Thu, 3 Jul 2008
widl: Consolidate top-level parameter conformance/variance expression writing into a separate function.

Descend through as many pointer types as necessary to find the fundamental type and determine whether it needs a top-level parameter conformance/variance expression to be written. Add support for writing top-level parameter conformance/variance expressions for non-encapsulated unions.

- Rob Shearman <robertshearman@gmail.com> Fri, 4 Jul 2008
widl: Rename find_type_helper, find_type and find_type2 to find_type, find_type_error and find_type_error2 respectively.

- Rob Shearman <robertshearman@gmail.com> Fri, 4 Jul 2008
widl: Remove some unnecessary calls to duptype.

- Alexandre Julliard <julliard@winehq.org> Mon, 7 Jul 2008
widl: Fix a couple of uninitialized variable compiler warnings.

- Alexandre Julliard <julliard@winehq.org> Mon, 7 Jul 2008
Add noinput directive to all lex files to avoid a compiler warning.

Note: Two patches are missing because they implement code to generate MIDL-incompatible SEH support code. Unfortunately I think it is almost time to fork WIDL because later patches implement even more incompatibilities. :-(
