I think you read it right. Mostly.

I still have this issue here. See this:

If running a java program on a JVM means linking to the JVM,
then the java program links to cygwin.a too (let alone .dll).
But the the exception is for OpenSource(tm) programs only.
Though if the java program is not OpenSource(tm) licensed
then we're not allowed to use the exception, so we fall under the GPL
and we're not allowed to run this non-OpenSource(tm) program.

It means that on SableVM on Cygwin we can run GPL-incompatible programs,
BUT they have to be OpenSource(tm).

So... anybody to polish the SableVM Cygwin port? :-)

I'd be glad to help.
