The iostreams module mapped_file.cpp fails to compile on (at least) Solaris because it makes use of the mmap flag MAP_FILE which does not exist on that platform. I think this should be protected in an #ifdef MAP_FILE block or similar.

I'd say so its not available on SGI and under Linux (RH9) from man mmap:

MAP_FILE Compatibility flag. Ignored.

IEEE Std 1003.1, 2003 Edition http://www.opengroup.org/onlinepubs/007904975/functions/mmap.html

has no mention of it either

This seems to be a flag I inherited from Craig Henderson. I've removed it; I'll see how the new version works. Jonathan
