Hi Corinna,

In partial response to this and the discussion you were having with 
Alexandre Olivia regarding gcc-3.4 pch problems under cygwin.

After looking at the VMM kernel services documentation for 9x*: 
http://msdn.microsoft.com/library/en-us/w98ddk/hh/w98ddk/kernel_8t4m.asp

It might be possible to overcome 9x's native memory mapping limitations 
by supplying our own hooks to the 9x's system API.  FWICT, it seems like 
the kernel level provides a wealth of memory management, mapping, and 
locking functionality that just isn't currently available to userspace 
via conventional means.

While googling, I also ran across this article which I found to be quite 
informative on the subject of memory mapping and how to deal with the 
64kb-boundry limitations of MapViewofFile for Win9x/Me/2k/XP:
http://freespace.virgin.net/james.brown7/tutorials/bigmem01.htm

Maybe it is of some use?  I could be wrong.

Cheers,
Nicholas

distributed before they removed it for the newer NT-only versions.
