It would be a lot easier if you included the actual g++ command output,
not whatever useless mangled version comes from your IDE.  From your
attachment, that is:

In file included from
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../include/w32api/windef.h:246,

[ Note: you are using Windows paths and defining WIN32, all of which
implies that you are making a native Windows program.  You should be
using MinGW if this is your goal, not Cygwin.  But that's not relevant
to your question. ]

Line 182 of winnt.h is:

typedef BYTE BOOLEAN,*PBOOLEAN;

If it's choking on this typedef that means your namespace is polluted,
i.e. some other header or source file has already defined a type or a
macro named BOOLEAN prior to the point where the winnt.h header file is
included.  We would need to see your source code (or at the very least
the order of includes) to know anything more.  It would also be good to
look at the preprocessed source of the file, which helps debugging macro
namespace issues.  You might also be able to use WIN32_LEAN_AND_MEAN to
work around this but I don't recall what exactly it disables.
