wxmotif

Hello,

I'm just trying to build M with wxmotif (svn head) for fun:

/a/M/M/include/gui/wxllist.h: In constructor 'wxLayoutDataObject::wxLayoutDataObject()':
/a/M/M/include/gui/wxllist.h:1324: error: invalid conversion from 'const wchar_t*' to 'Atom'
/a/M/M/include/gui/wxllist.h:1324: error:   initializing argument 1 of 'wxDataFormat::wxDataFormat(Atom)'

Regards,
Nerijus

 If you're still interested in pursuing this (although I really wonder
why...), you should just remove the _T() at this line, this string doesn't
have to be a Unicode one.

Then
/a/M/M/include/gui/wxllist.h: In constructor 'wxLayoutDataObject::wxLayoutDataObject()':
/a/M/M/include/gui/wxllist.h:1324: error: invalid conversion from 'const char*' to 'wxDataFormat::NativeFormat'
/a/M/M/include/gui/wxllist.h:1324: error:   initializing argument 1 of 'wxDataFormat::wxDataFormat(wxDataFormat::NativeFormat)'

 Just make the conversion explicit, either by writing

	SetFormat(wxDataFormat("xxx"));

or

	SetFormat(wxString("xxx"));

This is needed because wxDataFormat is constructible from wxString and
wxString is constructible from char* but the compiler won't use 2 implicit
conversions automatically, just one.
