No GCC is compliant, MS is not.
This is illegal in C++ according to section 9.5 of std.
struct a {
union /* anon */ {
struct b_struct {
int c;
};
int b_int;
};
};
struct b_struct has to be defined outside of anon union namespace (ie
non-static wrt to the union).
The two types in w32api that violate this are PROCESS_HEAP_ENTRY in
winbase.h and REPARSE_DATA_BUFFER in winnt.h

Yes, I will have some sleep and then look at my changes again first
though. Also, as before, involves a define in cygwin.h (ifdef
WIN32_BUILD_RELOCATABLE_PACKAGE, as per Mumit's diff to 3.0) to prevent
some undefs of command line macros.

C dll patches applied and test okay. Still ICE making C++ dlls with
this syntax: 'class __attribute__(dllexport) foo'. Mumit's patch
prevents SEGV.

Yes I will get fresh diff after the sleep and assuming I can get decent
connection to server.
