Comment:

 configure might be setting HAVE_SYS_MMAN_H incorrectly.

 When you run configure, do you have any configure lines that mention
 mman.h, mmap, munmap, or getpagesize?

 Clearly you have some header than mentions mmap and munmap.
 Do you need to link to a special library to get access to mmap and munmap?

 Do any of your headers mention getpagesize?

 What happens when you disable HAVE_SYS_MMAN_H in orconfig.h?
