Hello!
Recently I have a lot of fun trying to build coda-6.0.12 with 
heimdal-0.7.1 (the latest version). Coda compiles fine with it but auth2 
can not start. It dies from the beggining somewhere in LWP while doing 
swapcontext. The problem was that the new heimdal is automatically built 
with pthread support if pthread library is found. Heimdal is functional 
in either case (with pthread support enabled or explicitely disabled 
during configuration) but coda works only with heimdal without pthreads.
Don't know  whose bug this is, but I decide to post this message for 
those who would like to step over rakes after me.
