BTW, the project broke while I was trying to use Digital Mars C instead wondering if its funny behavior was due to a bug in the C compiler I was using.

there is no snn.lib in open watcom or watcom v11, 10, 9, 8 or 7.

Hi! A short while ago, I had a problem with Open Watcom saying the mentioned file was missing. I restarted my system then reinstalled Open Watcom but to no avail. I tried another project and didn't get the error. I replaced the problem project's project file, and the problem still appeared. I had to revert to an earlier state in the project and replace some files that changed, and now everything's fine.

I searched the sources, there is no mention on SNN of any kind. Sounds like your build scripts try to pull it in. Which command are you executing?
