Hello,

My application uses fopen to open a lot of files. While in linux
opening and reading thousand of files doesn't even take a second; in
cygwin it takes more than 5 seconds.

I think it is because path conversion functions in cygwin dlls. 'open'
function is a bit faster. If I use -mno-cygwin it becomes very fast
but I can't use it.

Is there an easy way to make cygwin dlls just open files; without any
linux-windows conversion?

Erdem
