It is the one possible solution, MEMORYSTATUSEX is defined by the
mingw.org compiler in winbase.h which is included by windows.h, and
looking at the definition:
#if (_WIN32_WINNT >= 0x0500)
typedef struct _MEMORYSTATUSEX {
DWORD dwLength;
DWORD dwMemoryLoad;
DWORDLONG ullTotalPhys;
DWORDLONG ullAvailPhys;
DWORDLONG ullTotalPageFile;
DWORDLONG ullAvailPageFile;
DWORDLONG ullTotalVirtual;
DWORDLONG ullAvailVirtual;
DWORDLONG ullAvailExtendedVirtual;
} MEMORYSTATUSEX,*LPMEMORYSTATUSEX;
#endif
The current w32api provided by mingw.org defines _WIN32_WINNT as
WINVER and WINVER is defined as 0x0400, so it won't pick up this
struct.
Another way this could be handled is by define _WIN32_WINNT in the
.mak files. In fact in the Make_ming.mak file WINVER is defined as:
# Set the default $(WINVER) to make it work with pre-Win2k
ifndef WINVER
WINVER = 0x0400
endif
So adjusting it in the source would be ineffective anyway, you should
just adjust WINVER in Make_ming.mak.

Chris
