Strange max. mapping address for mmap() with MAP_FIXED

[Martin Corino <mcorino at remedy dot nl>]

Hi,

Is there any reason why the maximum address value I can use for mapping 
shared memory is 0x9ff0000. 
If I go beyond that (f.i. 0xa000000) I get "Value too large for defined data type".

I call "mmap(<address>, 4096, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, <filehandle>, 0)".

I'm using the latest release of Cygwin supplemented with the snapshot of 
Oct. 26 (cygcheck output attached).

regards,
Martin.
