Don't assume we know what this is. Explain, or point to a reference. By the way, Cygwin's C library is newlib, so if this is a C library change, you would have to submit it to the newlib project, and it would automatically appear in Cygwin once it was accepted into newlib. > 2) If I set up a pipe between two applications, there seems to be limit to > how much I can send through it in one go, I'm not sure what the limit is but > under linux / bsd I regularily send through 13MB arrays in one go.

See cygwin-apps@ archives. Aspell packages are in the pipeline. > 4) Finally, a notational issue :) In my application I use bzipped files.
