Thanks for the bug report. That one rang a bell :)

In theory, there PROT_* values should be in <sys/mman.h>. Are they there 
on your system? Does configure find the include file in your config.log?

I've fixed a compilation problem on Cygwin on 13th june that dealt with 
a similar problem. Check out this thread:
http://thread.gmane.org/gmane.comp.java.vm.kaffe.general/5035

The ChangeLog entry was:
2004-06-13  Dalibor Topic  <robilad at kaffe.org>,

         * configure.ac:
         Check for <sys/mman.h>.

         * config/config-mem.h:
         Include <sys/mman.h> if it is available.

         * configure,
         config/config.h.in:
         Regenerated.

         Reported by: Bjørn Wennberg <bjornw at bouvet.no>
