Обсуждение: Postgres Compilation Error

Dear Friends,       I am trying to compile postgresql to an ULTRA 10 machine operated
by the Solaris system. I face this error in compilation that I cannot fix. 
Please if you can help me, reply soon. Thank you for concern and looking
forward to hearing from you.
