Hi
I always run gcc with every possiable warning message turned on. I have
been getting several (2) messages about "redefining" things. I have
modified three of the standard header files to eliminate this problem and
have included them here. It would be nice if these changes could make it
into a future software release.
<<unistd.h>>

bye...............eric
