Hi Torsten,

You have to distinguish between the Cygwin tools, that many find useful, and the Cygwin compile-time environment. I think Ralph is saying is to drop support for the Cygwin gcc compile environment, and require use of the Microsoft compiler. Thus the executables don't depend on the Cygwin run-time environment, which is a moving target.

As an example of the mixture you can still end up with, I know for a long time we depended on a Cygwin version of gmake, but the compiler was still the Windows compiler.

Cheers,

Hej,

 From my experience cygwin has some advantages over native Windows,
like scripts, Perl, POSIX path names, long path names, xemacs..

Are there any chances to give us an overview, which problems, troubles, .. ?

That could ease the motivation for a decision, whichever that would be.
