CC=cc ./configure on a solaris 7 system results in...

  configure: error: pthread.h and pthread_create are not compatible

I found a similiar problem reported this past Feb in the email archives for
Digital Unix (software bugs/62).  The workaround (I _think_) is similiar, but
with a potential problem.

CC=cc LIBS="-lpthread"  ./configure

This works, but someone ("Kurt D. Zeilenga" <Kurt@OpenLDAP.Org>) in
the aformentioned article mentioned that doing this was a bad idea. To quote

Can someone comment on this?  Am I digging a bigger whole?  Is there a better
way to resolve this problem?

Thanks.
