So there appears to be something wrong with cygwin1.dll
built with the current build tools (gcc 11.2.0, binutils
2.37, not sure what else is relevant).
Wait a minute...I'll bet this is related to the MEM_EXTENDED_PARAMETER
initialization problem that was dealt with in commit bdb7991db.
More data: When I run the test case under gdb, it succeeds. When I run it
under strace, I see VirtualAlloc2 in fhandler_dev_zero::mmap failing with
windows error 87.
Are the const's I added to the MEM_EXTENDED_PARAMETER data invalid,
perhaps?
I tried removing them, and I got the same error. I also tried removing static,
and I tried removing both static and const.
