Subject: [svn-r5215] Purpose:     Bug fix Description:     Zlib-compression
 was reported according to if a Z-library (e.g., libz.a)     has been found. 
 It actually needs the presence of a valid zlib.h header     file and the
 compress2() routine. Solution:     Changed the IF_YES_NO to be more general
 by accepting multiple arguments     and changed the Zlib-compression depends
 on zlib.h header and the     compress2() routine. Platforms tested:    
 Eirene.
