I've bumped into this myself.

I added an old fix for that from the mailing list to my fork 
(http://landley.net/code/tcc).  I'm not working on that any more because it's 
out of sync with cvs, but you can get a mercurial repository from that 
directory (with static-http://) that gives you all the individual broken out 
patches I collected.

My fork had that fixed too.  There should be a snapshot tarball in that 
directory if you don't like mercurial.
