AW: [En-Nut-Discussion] 3.4.2release os/timer.c (1.3.2.2) bug

[Oliver Schulz]

Hi,

obviously it is "just" a mistyped bit name.

I'm very sorry that this bug was published with Nut/OS release 3.4.2.
Some seconds ago, a commited a corrected version of os/timer.c into CVS.

I think, the automatic tarball generation is a very good idea, a helps a lot
of people, who don't want to setup a complete CVS environment...

So long,
Oliver.
