Hi,

I have read [1] and set heap_chunk_in_mb to 2048, but
max_memory.exe gives me only 1920 MB. I need (almost)
2048 MB to be able to manipulate BIG (map) images, how
can get 2048 megabytes available for my program?

Where has the 128 MB (2048 - 1920) gone? I also tried
increasing heap_chunk_in_mb to 4095, but max_memory.exe
still gives 1920 MB.

I'm running cygwin with 64-bit Windows 7 Ultimate in a
machine that has 4 GB of physical RAM, and lots of swap.

[2] says native 64-bit cygwin is not being planned, is
this still the situation? Or /LARGEADDRESSAWARE support,
would it increase memory available for cygwin apps [3]?

-Paavo
