The visibility stuff isn't enabled by default.. partly because it's a 
gcc 4 feature and at the time I didn't have a gcc 4 box to test it on, 
and partly because it I haven't proved it doesn't break stuff.  You can 
try it with --enable-visiblity and see what happens I guess.

I can get loads of those now - just setup a new server to test this on. 
  I've verified it doesn't work but can't guess why.

I suspect the traditional method of compiling those librararies later in 
the build and explicitly linking them to cvsapi will fix it... OTOH it's 
been working fine up to now without needing to do that.
