Well.. now it works -- beats me why it didn't before!

Anyway -- attached is take - um - 4 I think; implementation moved into
xc_linux.c and xc_solaris.c (I chose not to go with the default

null version on Solaris). No changes in tools/xcutils. I also removed
the xc_ prefix from the routine to make it clear that it's internal...

used for the save/dump file.
