[ace-users] Unable to run simple ACE programs in cygwin

[Johnny Willemsen]

Hi,

The cygwin port is really experimental, we do know that there are a lot of
runtime issues. Have a look at the old test stats for cygwin at the link
below, you will see there that there are a lot of test failures. There are
no plans at this moment for cygwin from our side, we do need funding to work
on this port, maybe you can provide patches to improve the port
