I've checked in a patch. I'd be glad if you could have a look into it.
Thanks again for your analyzis. It's highly appreciated,

I've just fixed the conditional for now. I th

Use this address when calling MapViewOfFileEx(). If the call fails
and MAP_FIXED is not set, then try again with addr = 0.
Yes, that's what I mentioned in my first reply. I

So it can't rely on getting the mmap at the same loc
I've been trying to get the new gcc PCH code working on Cygwin.
The gcc PCH implementation works by using mmap() to quickly
resurrect the precompiled header when compiling on a new file.
To allow this to be done quickly, mmap() is used when creating the
precompiled header and the precompiled infor
