With libyui-ncurses, at least, I see this when preprocessing YNCursesUI.cc:

# 143 "/usr/include/etip.h" 3 4
class NCURSES_CXX_IMPEXP NCursesPanel;
class NCURSES_CXX_IMPEXP NCursesMenu;
class NCURSES_CXX_IMPEXP NCursesForm;

class NCURSES_CXX_IMPEXP NCursesException
{
...

That is, the macro NCURSES_CXX_IMPEXP has not been expanded.  It is
defined in /usr/include/cursesw.h.

The problem seems to be that libyui-ncurses has its own copy of
/usr/include/cursesw.h, named src/ncursesw.h, but the definitions in
it are not an exact match for the system header file.  It pulls in the
system etip.h, and the mismatched definitions cause the errors you are
seeing.

A simple workaround is to add this to the top of %build:

export CXXFLAGS="-DNCURSES_CXX_IMPEXP= %{build_cxxflags}"

but the real fix would involve reconciling the libyui-ncurses code to
the latest GNU ncurses headers.

I haven't looked at libyui-mga-ncurses, but if the same fix doesn't
work, ping me and I'll take a look.  Regards,
