Hi,

In trying to use RSXNTDJ 1.3.1/DJGPP 2.01/MS Platform SDK to create
Win32 programs, I've encountered the following problem:

Quite a few of the Platform SDK include files are written to take
advantage of the VC++ anonymous union feature (which compiles the code
"struct x { union { int y;};} z; z.y = 10;").  Although the header files
are written in a way so that one can write portable code (look at
prsht.h), almost all the sample code available (e.g., from the MSDN) are
written for the VC++ compiler only.

I was able to compile some elaborate programs from the Windows 95 User
Interface book, including one that uses the treeview control.  However I
have to modify others, just to get a clean compile under gcc.

My question is: does GCC support anonymous unions?  How do I turn it on?

By the way, RSXNTDJ 1.3.1 looks very good.  Thanks to the DJGPP/RSXNTDJ
community!
