"Don't do that. Use 64 bit Cygwin whenever possible. 32 bit is a lost cause."
I would like to mention why I am still using 32 bit Cygwin.
I maintain a port of a database called GT.M
(https://en.wikipedia.org/wiki/GT.M) on Cygwin. I work with Electronic
Medical Records that run on this database. GT.M contains a large
amount of assembly code, written to run on the x32 Linux ABI and the
AMD x64 ABI. It's was very easy to get the x32 Linux ABI to run on
Cygwin x32; Cygwin x64 on the other hand uses the Windows x64 ABI,
which is very different than the AMD ABI (more detail here:
I don't have the expertise nor the time to rewrite a lot of assembly
code to use the Windows x64 ABI. There are about 100 source code files
that are in assembly.
By the way, thank you for the Async IO APIs. I needed those for newer
versions of GT.M and was able to port it successfully to Cygwin x32.
