missing definition PAGE_TARGETS_INVALID winnt.h
I was compiling code for mingw and the code made a reference to PAGE_TARGETS_INVALID.
I found it defined here: https://docs.microsoft.com/en-us/windows/desktop/memory/memory-protection-constants
#define PAGE_WRITECOMBINE 0x400
+ #define PAGE_TARGETS_INVALID 0x40000000
I looked at cygwin, but I didn't find winnt.h in their stuff.
Thanks. I notice that PAGE_TARGETS_NO_UPDATE, (which appears to have the same value), is also conspicuous by its absence. I've added both to my local copy of the WSL repository, so they'll be included in my next push, and thus, in the next WSL release.
